Adobe have passed the development and support of AIR to Harman but AIR is still an active and valid platform.

Unfortunately, now that Adobe have passed AIR to Harman, they have removed their regular Adobe AIR download page (redirecting users to the Harman site) and, at the moment, Harman provide only an AIR SDK (a Software Development Kit for developers) but not an AIR runtime (for AIR application end users).
Installing an AIR SDK will not allow you to run the JuiceboxBuilder installer. An AIR runtime is required.
This makes life a little difficult during this transitional period.

However, it is still possible to download the most recent AIR v32.0.0.125 runtime directly from Adobe via the links below:
Mac: https://download.macromedia.com/air/mac … obeAIR.dmg
Windows: https://download.macromedia.com/air/win … taller.zip

Once you have downloaded and installed AIR from the links above, you should be able to pick up the Installing JuiceboxBuilder instructions at Step #2.

At the moment, although Harman provide only an AIR SDK, they hope to provide an AIR runtime very soon.
According to a comment (from five days ago) on this web page, Andrew Frost (Harman's Software Engineering Manager) says:

In the meantime, until the Harman AIR runtime is made available, the most recent Adobe AIR runtime can be downloaded from the links above (or from software download sites such as Softpedia). However, if you download Adobe AIR from any website other than Adobe's own, then please do so at your own risk.
Incidentally, the most recent Adobe AIR beta runtimes (v32.0.0.144) can still be downloaded from the Adobe Labs page here.

I have notified the Juicebox developers of Adobe's website change and our installation instructions should be updated in our next website refresh.

Yes, but you'll need to implement the fix (first required for MacOS Catalina) noted here.

I hope this helps.

It sounds like a caching problem: either client side (in your browser) or server side.
Caching can be very useful but it can also be a hindrance when developing a web site.

First of all, try completely clearing your browser's cache before reloading your gallery's web page to ensure that your browser is using the latest versions of all the files fresh from your web server (instead of older, cached versions).
Alternatively, try viewing your gallery's web page using a different browser (one that you have not used to view your gallery's web page before): Chrome, Edge, Firefox, Opera or Safari.

There is a chance that your web host uses server-side caching and even though you upload new files via FTP, older versions of those file could still be served to browsers for a certain amount of time.

I have an account with a web host that uses Varnish server caching. After I upload a new version of a file to my web server, the new version is not seen (and the old version is still served) for about 20 minutes afterwards. For this reason, I have Varnish disabled.

Ask your web host if they have server-side caching enabled on your hosting account and, if so, ask if they could disable it.

If neither of the suggestions above help, then please post the link to your gallery's web page and let me know what you see and what you expect to see.
I'll take a look myself, let you know what I see and hopefully figure out what the problem is.
Thank you.

You'll likely need to run whatever editing program you use as an administrator (as well as being logged  on as an administrator).
Rather than just double-clicking your editing program's shortcut, right-click it and select 'Run as administrator'.

Incidentally, after opening your editing program via 'Run as administrator' you may not be able to drag and drop the 'index.html' file into the program. You may need to use the program's 'File -> Open' functionality to open the 'index.html' file instead.

I hope this helps.

If you edit a gallery using JuiceboxBuilder-Pro, then the only thing you need to update on your web server is the gallery's 'config.xml' file (which holds the gallery's configuration options and image data). (You'll also need to update the 'images' and 'thumbs' folders if you add any new images, though.)
There is no need to update the gallery's embedding code (unless you change the gallery's background color or dimensions) so you can leave this in place on your web server with no need to overwrite it with a version that does not contain the themeUrl.

If you use the gallery's own 'index.html' page (generated by JuiceboxBuilder-Pro) to display the gallery on its own web page (rather than embedding the gallery in an existing web page alongside other content) and are in the habit of uploading the entire gallery folder to your web server after editing, then you can modify the template file that JuiceboxBuilder-Pro uses to generate the 'index.html' page so that the themeUrl is present in every gallery you create and edit.

Open the following file in a plain text editor and add the themeUrl to the embedding code:
Windows: C:\Program Files (x86)\JuiceboxBuilder-Pro\template\index.html
Mac: /Applications/JuiceboxBuilder-Pro.app/Contents/Resources/template/index.html

For example:

<!--START JUICEBOX EMBED-->
<script src="jbcore/juicebox.js"></script>
<script>
    new juicebox({
        containerId: 'juicebox-container',
        galleryWidth: '%%WIDTH%%',
        galleryHeight: '%%HEIGHT%%',
        backgroundColor: '%%COLOR%%',
        themeUrl: '/my_themes/custom_theme/theme.css'
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

The leading slash in the themeUrl above denotes your root directory (i.e. the themeUrl is a relative path always starting at your root directory) so such a themeUrl would work in any page throughout your website without modification.

First, create a Juicebox gallery with JuiceboxBuilder (the desktop application to create and edit galleries).
You'll find details in the links below.

JuiceboxBuilder Tour: https://www.juicebox.net/tour/juiceboxbuilder/
JuiceboxBuilder User Guide: https://www.juicebox.net/support/juiceboxbuilder/
Getting Started Guide (inc. 5 minute video): https://www.juicebox.net/support/#getting-started

Then, you can either:
(1) View the gallery on a web page of its own by opening the 'index.html' file (inside the gallery folder) in a browser.
... or:
(2) Embed the gallery into an existing web page (alongside other content) by following the instructions in the Embedding Guide: https://www.juicebox.net/support/embedding/

Take a look at the short Adding a Logo support section for ideas as to how you could incorporate a logo into your Juicebox gallery.

If you use Suggestion #3 from the link above, then you can also make the logo into a link by using a Gallery Title such as:

<a href="http://www.example.com/index.html"><img src="mylogo.png"/></a>

As an alternative to using the Gallery Title, you could use the Back Button.
Set and backButtonUseIcon="FALSE" and the backButtonText will be used. instead of the 'home' icon. You can then set the backButtonText to be something like the HTML code above. (Also, be sure to set backButtonPosition to something other than NONE so that the Back Button appears in the gallery.)

For reference, a list of all Back Button options can be found here.
More information on using HTML formatting within the Gallery Title and Back Button can be found in this FAQ:
How do I add HTML formatting to the Gallery Title or Back Button?

I hope this helps.

Technically, there really is no limit to the number of galleries that you can have on a single web page. (There is no hard-coded limit built into Juicebox.)

This sounds like a coding problem (maybe a duplicated baseUrl or configUrl).
Please post back with the URL to your web page so that I can see the problem for myself and hopefully help further.

Incidentally, when embedding multiple galleries, the 'juicebox.js' file should be loaded just once (i.e. once per web page rather than once per gallery). If you currently load the 'juicebox.js' file once per gallery, then leave the first instance and remove al others.

Thank you for the update. I'm glad you've been able to resolve your Lite/Pro problem.

You have two opening <script> tags one after another: one on line 97 and the other (after a few blank lines) on line 103.
After the initial opening <script> tag, the browser is expecting some JavaScript code but, instead, it encounters the '<' character of the next opening script> tag which is where the error is coming from.
Just remove one of these opening <script> tags and all should be well.

If you'd like to check your web page for any other HTML errors, you can feed your web page's URL to the W3C Markup Validation Service (and then fix any errors reported).

That's a strange solution, for sure, but I'm glad that it worked for you. Thank you for letting me know.

Incidentally, I just reinstalled Windows 10 myself last week (a clean install) and did not have to adjust my system clock to install JuiceboxBuilder-Pro so I'm really not sure what the cause of the problem is.
In any case, I'm glad you've got it working.

You're welcome!
I hope you get on OK with your other galleries.
I'll mark this thread as [SOLVED] but if you run into any further problems, just create a new thread and I'll do my best to help you out.

Yes, your gallery at http://davebreen.com/jhbsocber20.html now displays correctly. If you do not see your gallery at this address, then please completely clear your browser's cache before reloading your gallery's web page to ensure that your browser is fetching the current files from your web server (and not using older, cached versions from your computer's hard drive).
(The gallery is working so if you do not see it, the issue if most likely a browser caching issue.)

PHP is a server-side scripting language. Some web pages may contain PHP code. The PHP code is processed on your web server before the web page is delivered to the user's browser. This allows for a dynamic (rather than just a static) website.
If any of your web pages use PHP, then you'll need to have PHP installed on your web server.
For example, WordPress is a PHP web application which requires PHP. It will not work without PHP.
Juicebox-Pro requires PHP for two functions, namely the Download Button and Password Protection. PHP 5.2 or later is required for these functions but, if you do not use them, then your Juicebox gallery will run quite happily without PHP being available.

When you visit any URL which does not exist on your web server, your web server defaults to displaying the "WordPress Coming Soon" page as your site's error 404 (file not found) page. You can change this error 404 page if you like but you'll need to find out where it is being set on your web server. (Your web host should be able to help you out with this.)

WordPress is a PHP web application which allows users to create a website or blog online in a web browser interface.
You do not need WordPress installed in order to have Juicebox galleries on your website.
However, if you do use WordPress, then there is a dedicated Juicebox plugin for WordPress (WP-Juicebox) which allows you to create and embed galleries into WordPress pages and posts from within the WordPress interface (without having to build your galleries on your computer with JuiceboxBuilder).
If you do not want to use WordPress for your website, then there is absolutely no need for it in order to have Juicebox galleries.

If you installed WordPress through your online hosting account's control panel, then there may be a way to uninstall it through the control panel, too. I'd investigate this first (ask your web host, they'll know) before you start manually deleting any files.

From what I've seen of your website and the changes you've made, I do not see any evidence of server-side caching but if you make any changes and don't see them immediately, then it's just something to bear in mind which might be causing the problem.

As I mentioned above, your http://davebreen.com/jhbsocber20.html gallery is now displaying and functioning fine and if you don't see it yourself, then please try clearing your browser's cache before reloading your gallery's web page.

I hope my notes above help to clarify a few things.
If you are having trouble with any other galleries, just post links to them and I'll try to help further.

As far as I can recall, the minimum Adobe AIR requirement for JuiceboxBuilder is AIR v2.0 or later so you should hopefully be able to download the last version of AIR for Linux (v2.6) from the Adobe AIR archive web page and install JuiceboxBuilder under this version of AIR.
Here's a direct link to Adobe AIR v2.6 for Linux (from the link above).
I hope this helps.
