Your web page loads the 'juicebox.js' file for each gallery. The 'juicebox.js' file should be loaded only once per page.
Try removing the following line from your second gallery's embedding code:

<script src="../141019_tagderoffenentuer_juicebox/jbcore/juicebox.js"></script>

This should solve your problem.

The Juicebox gallery's icons are characters in a custom font and they are inheriting the color from the following code in your 'sakura.css' file:

p, div, h1, h2, h3, h4 {
    font-family:"Times New Roman", Times, serif;
    font-family: Arial, Helvetica, sans-serif;
    font-weight:normal; 
    font-size:14px;
    line-height:140%;
    color:#888;
}

Rather than applying these CSS rules to all p, div, h1, h2, h3 and h4 tags on your web page (which will include those within your Juicebox gallery), apply them instead to only those elements which require them through use of ids and classes.

I'm sorry to hear that you're still unable to use JuiceboxBuilder-Pro.
Thank you for trying the beta and older versions of Adobe AIR.

Clearing the ELS folder has been known to fix the problem of non-responsive buttons on the 'Start' tab but it looks like this does not work in your case.

Please take a look at this forum thread.
It contains a fairly comprehensive list of things to check and try for users who are experiencing difficulties installing JuiceboxBuilder-Pro. I realise that this is not the same problem that you are facing but perhaps one of the suggestions will help.

However, I'm glad that you have found an alternative way to create your Juicebox-Pro galleries.

Open your gallery's 'index.html' file in a plain text editor and change (or delete) the contents of the <title></title> tags.
If you create your galleries with JuiceboxBuilder-Pro, then the Gallery Title should automatically be used as the browser title.
Most plugins also use the Gallery Title (rather than the default text 'Juicebox Gallery') so please double-check your Gallery Title before saving your gallery and make sure that you are using the most recent version of JuiceboxBuilder-Pro (v.1.4.3) or whatever plugin you use to create your galleries.
I hope this helps.

Please see the reply to your other query in this forum thread.
Hopefully this will solve your problem.

If the suggestion in the forum thread does not help, then please check the following.

(1) The icons in a gallery are characters in a custom font so please check to see if your web page sets a font-family for all elements on your web page using a global CSS selector, such as:

* { font-family: Courier; }

If this is the case, Juicebox will have no option but to inherit such a CSS rule. The font-family will apply to all elements on your web page, including those within your gallery. Try setting the font-family to the 'body' element of your web page instead (or better still, to only those elements on your web page which require it through use of ids or classes).

(2) Try re-uploading your gallery's 'jbcore' folder to ensure that all the font files (in the 'jbcore/classic/fonts' folder) are present and correct on your web server (in case something happened during the initial upload resulting in corrupt or missing files).

Also, I notice that your gallery uses Juicebox-Pro v1.4.2.
You might like to upgrade your gallery to v1.4.3. Full instructions for downloading the latest version and for upgrading existing galleries can be found on the Upgrading Juicebox support page.
More information about v1.4.3 can be found in this Juicebox blog entry.

I notice in the Adobe forums that other users seem to be having problems with AIR and AIR applications under Yosemite so Adobe may be currently having issues with AIR on the new Mac OS.
You might like to try using the latest beta version of Adobe AIR which can be downloaded from here: http://labs.adobe.com/downloads/air.html
You could also try reverting to an older version of Adobe AIR (such as v15) to see if this helps. Older versions can be downloaded from their archive web page here: http://helpx.adobe.com/air/kb/archived- … rsion.html
I do not know if this will help but it might be worth trying.

Not directly via the plugin's interface. The Lightroom plugin works only with local images and there are no Flickr options in the interface.
You could, however, create a gallery using the Lightroom plugin (using a sample image or two just so that it works) and then open the gallery's 'config.xml' file in a plain text editor and add your Flickr configuration options as attributes to the opening <juiceboxgallery> tag, e.g.:

useFlickr="TRUE"
flickrUserName="your_flickr_user_name"
flickrTags="tags,go,here"

Please make sure that you using an Administrator User Account and then try the following:

• Uninstall Adobe AIR.

• Download the latest version of Adobe AIR from here: http://get.adobe.com/air/

• Install Adobe AIR by right-clicking the 'AdobeAIRInstaller.exe' file and selecting 'Run as administrator'.

• Now try installing JuiceboxBuilder-Pro following the instructions in the JuiceboxBuilder-Pro User Guide.

WP-Juicebox displays all images attached to the post containing the gallery.
The process you are using:

... will simply insert existing images from the Media Library images into the post. (It will not attach images to the post.)

You should follow the 'Adding Images From WordPress Media Library' instructions on the plugin's support page here.
Essentially:
(1) Click the 'Add Media' button above the toolbar.
(2) Drag and drop images from a folder on your computer into the media window and wait for them to finish uploading.
(3) Close the media window (with the cross at the top right corner).  (Do not click the 'Insert Into Post' button.)
(You can change the order of the images by selecting 'Uploaded to this post' in the media window and then dragging and dropping the thumbnails.)

Please note that WordPress allows each Media Library image to be attached to only one post so it is not possible to include images from the Media Library which are already attached to other posts.

The MD5 hash for the current (v1.4.3) 'JuiceboxBuilder-Pro.air' file is 4ff2a4c89ee2f4c8bc35fe72ba6a1288 so it seems that your JuiceboxBuilder-Pro installation file may be corrupt or incomplete.
Did you encounter any errors whilst unzipping the Juicebox-Pro download zip package?

Try downloading the Juicebox-Pro zip file again (using the link from your purchase email), perhaps using a different browser this time (Chrome, Firefox, Internet Explorer, Opera, Safari).

Also, please see the note regarding the error message you encountered in the Installation Issues of the JuiceboxBuilder User Guide.

If nothing happens when you click the 'New Gallery...' or 'Open Gallery...' buttons on the 'Start' tab, then I would normally recommend the following, although it sounds like you have already done this:

(1) Uninstall JuiceboxBuilder-Pro.
Mac: Delete the 'JuiceboxBuilder-Pro' file from the Applications folder and empty your Trash.
Windows: Use the uninstaller in the 'Control Panel -> Programs -> Uninstall a program...' list.
(2) Delete the following folder manually:
Mac: /Users/your_username/Library/Application Support/Adobe/AIR/ELS/JuiceboxBuilder-Pro
Windows: C:\Users\your_username\AppData\Roaming\Adobe\AIR\ELS\JuiceboxBuilder-Pro
(3) Search your hard drive for the term 'JuiceboxBuilder-Pro' and delete any and all entries found.
(4) Reinstall JuiceboxBuilder-Pro.

Steps #2 and #3 should ensure that no files are left behind from any previous version or failed installation.

Please also check that you are using the current version of JuiceboxBuilder-Pro (v1.4.3) by going to 'Help -> About JuiceboxBuilder-Pro...' from the drop down menu at the top. If necessary, instructions for upgrading can be found here

If you continue to experience problems, then there is a fairly comprehensive list of things to check/try in this forum thread.

Hopefully one of the suggestions in the forum thread will help.

Yes, please.

If you want to suppress scroll bars on your web page, you can use the following CSS in the <head> section of your web page:

<style type="text/css">
    body, html {
        overflow: hidden;
    }
</style>

However, if content on your web page extends beyond the bottom of the browser window, then users will not be able to scroll down to see the hidden content.
If you want to ensure that your web page displays your header and gallery without the need for scroll bars (displaying the header with a specified height and using the remainder of the space for the gallery), then you might like to take a look at the online View Resizable Gallery with Top Menu Example sample in the Using a Resizable Gallery with a Header support section. You could view the source of the web page in a browser and copy/modify the code to suit your own needs (swapping the header content for your own header and the sample gallery for your own gallery).
