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).

Please re-download Juicebox-Pro v1.4.3 and upgrade your galleries with the new 'jbcore' folder.
Full instructions for downloading the most recent version and for upgrading existing galleries can be found on the Upgrading Juicebox support page.
We have just released a hotfix version of v1.4.3 which fixes the showImageNav=ALWAYS" bug.

Unfortunately, the lack of animation when firing the toggleThumbs() API method has not been fixed for v1.4.3 but it has been logged as a bug and is due to be fixed in a future version (although I do not know exactly when).

You need to assign your 'juicebox' object a variable name so that it can be referenced when using the API methods and events.
In my example above (and in the code that you have placed in your web page), the 'juicebox' object has been given a name of 'jb'.
Therefore, in your gallery's embedding code, just change:

new juicebox({

... to:

var jb = new juicebox({

It certainly sounds like your problems were web server related so hopefully your change of host will go smoothly and give consistent and predictable results.

You currently have two lots of embedding code (the new juicebox() section) on your web page (the code from my example above and your original code) and your original gallery is the one which is initially being loaded into the 'juicebox-container' div on your web page, essentially overriding the gallery from my example. You would need to integrate your own gallery into the rest of the code from my example. Also, your web page currently loads the 'juicebox.js' file after the custom JavaScript code. Try loading the 'juicebox.js' file before the custom JavaScript code.
Try the following in your web page as your complete embedding code:

<script src="/wp-content/uploads/juicebox/journalism/jbcore/juicebox.js"></script>
<script type='text/javascript'> 
    var fii = 1;
    var sm = 'AUTO';
    var thresholdWidth = 600;
    var jb;

    function loadGallery(fii, sm) {
        jb = new juicebox({
            baseUrl : "/wp-content/uploads/juicebox/journalism/",
            containerId : "juicebox-container",
            galleryWidth : "100%",
            galleryHeight : "100%",
            backgroundColor: "#000000",
            firstImageIndex: fii,
            screenMode: sm
        });
    }

    function setScreenMode() {
        var windowWidth = window.innerWidth ? window.innerWidth : $(window).width();
        var mode = windowWidth < thresholdWidth ? 'SMALL' : 'LARGE';
        if (sm !== mode) {
            sm = mode;
            fii = jb.getImageIndex();
            loadGallery(fii, mode);
        }
    }

    $(document).ready(function() {
        $(window).resize(setScreenMode);
        loadGallery(fii, sm);
        setTimeout(function() {
            sm = jb.getScreenMode();
            if (sm === 'LARGE') {
                setScreenMode();
            }
        }, 500);
    });
</script>
<div id="juicebox-container"></div>

Hopefully this will help.

You're welcome!
I'm glad you've got it working.
Thank you for posting back to let me know.
