I do not see this problem in Mobile Safari or Chrome on an iPod Touch 4 (or in any desktop browser)
What device do you see the problem in?

Try fixing the HTML errors on your web page to see if this helps.
You have a 'c' character at the very beginning of your web page before the Doctype Declaration.
When validating your web page, this results in errors such as "Stray doctype", "Stray start tag html" and "Stray start tag head" which may be causing problems in some browsers. Juicebox relies on the Document Object MOdel (DOM) to be intact. If the DOM is broken, Juicebox may not be able to find certain tags on the page (such as the 'head' and 'body' tags).

I cannot be certain that this will fix your problem but it is certainly a possible cause and errors on your web page should be fixed (for cross-browser consistency) anyway.

I'm glad that you have successfully been able to add a logo to your gallery.
Thank you for posting back to let me know.

The '7.xml' file (and all other numerical XML files in the 'uploads/juicebox/' directory) store settings for each gallery but they are not the actual XML files used by Juicebox when the galleries are displayed.

The XML files used by Juicebox when the galleries are displayed are generated dynamically by the 'config.php' file (with a 'gallery_id' query string so that Juicebox knows which numerical XML file to take the settings from) and it is because the plugin cannot access PHP files directly that the "Config XML file not found." message is displayed.

Try temporarily deactivating all plugins (other than WP-Juicebox) and reactivate them one-by-one (checking the functionality of your Juicebox galleries after each one) to see if you can find a conflicting plugin.

The problem seems to be one of security so if you have any security-related plugins, I would try disabling them first.

Please see the Adding a Logo support section for suggestions on how to incorporate a logo into a Juicebox gallery.

If you would like to remove the Juicebox branding from your gallery, you could purchase Juicebox-Pro. Pro galleries do not have the Juicebox badge/link in the lower-right corner.

This is not something that could easily be implemented just by setting a configuration option but it might be possible with the Juicebox-Pro API.
You could run some custom JavaScript code when the gallery is expanded using the onExpand(expanded) event.

jb.onExpand = function(expanded) {
    if (expanded) {
        // Gallery has been expanded. Do something.
    }
    if (!expanded) {
        // Gallery has been closed. Do something else.
    }
};

If I go directly to the PHP file which generates your gallery's XML data, an error 404 (file not found) is displayed.

This suggests that either the file does not exist on your web server, or that access to the file is being blocked.
This is the reason why both your gallery settings pop-up window (in the backend) and the gallery (in the frontend) do not display. They require direct access to the 'jb-config.php' and 'config.php' files respectively.
(This has not changed between v1.4.0.1 and v1.4.2.0.)

Please check the following:
(1) Check that all the WP-Juicebox files (including 'config.php' and 'jb-config.php') are present on your web server.
(2) Check that the permissions on these files are not too restrictive. (Permissions of 644 should be fine.)

Also, you could try checking with your web host to see if they have made any changes recently which would be affecting things this way.

I have created a test gallery using the same version of Juicebox as yourself (Juicebox-Pro v1.4.2) and exactly the same configuration options that you use in your own gallery but I have been unable to replicate the problem you are experiencing.

I do not know if it will help but I notice that your gallery's XML file includes largeImageURL entries but the corresponding images do not exist on your web server.
Try either uploading the 'images/large' folder to your web server or remove the largeImageURL entries from your gallery's XML file (either manually in a plain text editor or by editing your gallery in JuiceboxBuilder-Pro and deselecting the 'Large Images' checkbox before resaving your gallery). If Juicebox cannot find images that are specified, it may cause problems.

Also, in your email you say "I have been experiencing problems viewing JuiceboxPro  galleries on both an iPad and iPhone where they previously worked fine."
If your galleries were previous working OK but now do not and you have not changed anything yourself, then perhaps something has changed on your web server (maybe a configuration setting of some kind or an entry in your .htaccess file) which may be contributing to the problem. Please check with your web host to see if they have made any changes recently which would affect your hosting account.

Also, to try to determine whether or not a combination of configuration options is the cause of the problem, try creating a basic Juicebox-Pro gallery with JuiceboxBuilder-Pro using only default settings and upload that you your web server to see if this works OK.

Hopefully this will point you in the right direction as to what might be causing the problem.

As far as I am aware, the largeImageURLs will be used for the main display in the gallery if the display is retina and Large Screen Mode is being used. If screenMode="AUTO", Large Screen Mode will be used only if the device is not a small-screen mobile device (for example an iPhone) and the screen width is greater than 1000px.

Please check your email account's junk/spam folder to see if the email has been redirected to there. (With some email providers, it may be necessary to log in via their own web page to check the junk/spam folder as messages flagged as junk/spam may not be passed on to a client email program.)

If you still cannot find the email, then please contact support@juicebox.net and the admin team should be able to help you out further.

Thank you for reporting this problem. It has already been reported in this forum thread.

The double-paste issue seems to happen:
(1) Only on Mac (not on PC).
(2) Only when pasting via keyboard (not via mouse context menu).
(3) Only under Adobe AIR v14.0 (not previous versions).

I have notified the developers of this problem but it looks like there is, indeed, a problem with pasting via keyboard in Adobe AIR v14.0. Please see these links for further details:
https://forums.adobe.com/thread/1495749
https://bugbase.adobe.com/index.cfm?eve … id=3775354

In the meantime, workarounds would be to either:
(1) Paste the text via mouse context menu.
(2) Type the text into the input field.
(3) Paste the text via keyboard and manually delete the duplicate entry.
(4) Revert to a previous version of Adobe AIR (not necessary if using #1, #2 or #3 above). Previous versions of Adobe AIR can be downloaded from this web page.

Your Gallery Title is currently missing its closing </a> tag at the end of the link.

This is what the Back Button was designed for (but it is a Pro-only option). The Back Button icon can be seen in the top-left corner of this demo gallery.
With Juicebox-Lite, you could perhaps overlay a custom image link on top of your gallery (in the web page containing the gallery's embedding code) using HTML and CSS.

It is not possible to add a custom button to the Button Bar (in either Juicebox-Lite or Juicebox-Pro) or to include the Back Button as part of the Button Bar.

This is due to the way your gallery is embedded in your web page. You are loading your gallery's 'index.html' page into an <object> tag in your main page (which is essentially the same as loading a gallery into an <iframe>) and this will automatically disable the Expand Button. This is noted in the 2) Using an iframe section here.

If you were using Juicebox-Pro, you could use the Back Button to link directly to a page.
However, as a Juicebox-Lite user, you could turn your Gallery Title into a link by using HTML formatting as documented in this FAQ:
How do I add HTML formatting to the Gallery Title or Back Button?
For your Dimensional gallery, you could enter a Gallery Title in JuiceboxBuilder-Lite's 'Customize' section such as:

<a href="http://signsvictoria.ca/dimensional/">Click to open gallery on its own page</a>

As well as the Back Button and the Gallery Title, you can also add links to image titles and captions:

Social Sharing is possible with Juicebox-Pro. Please see here for details.

Your web pages are quite complex and load 4 external CSS files and 12 external JavaScript files (not counting the Juicebox files).
Depending on the size of all these files, they may take some time to load and for your page to initially be rendered in visitors' browsers.
