I think your problem is due to your site having 3 levels in its navigation menu (gallery index pages grouped under other gallery index pages). Showkase natively supports only 2 levels in its navigation menu and it is not possible to group a gallery index page under another gallery index page in the interface. A gallery index page can be only a top-level menu item.

Normally, when viewing a top-level page, the navigation menu displays all top-level links and also links to pages grouped under the current page. When you select a second-level page, the navigation menu remains the same.
Your problem seems to occur when you select a third-level page (a gallery grouped under a gallery index page grouped under another gallery index page). Everything in the navigation menu displays and works as expected until a third-level page is selected when the navigation menu displays only top-level links.
I'm not sure how you achieved a third level but Showkase was not designed to support or handle this. (It sounds like you would need a third row of links in the navigation menu and this is not something that Showkase has ever been able to do.)

As far as I am aware, there were no changes between v1.6.1 and v1.7.0 with regard to the navigation menu.
Perhaps you had made some manual modifications to the v1.6.1 source files (or maybe to your theme's 'custom.css' or 'custom.js' files) which were overwritten when you upgraded to v1.7.0.

If you are sure that v1.6.1 displayed the links in a way that v1.7.0 does not, then I would not ordinarily recommend using an older version of any software but maybe reverting to v1.6.1 might be the easiest remedy for your problem (as long as your site does not suffer from any of the bugs fixed in v1.7.0).

Incidentally, we have a dedicated Showkase forum here.

You're welcome!
I hope you're able to move your gallery's Button Bar to where you'd like it to be. (I thing using the CSS classes I suggested with negative margins and adding '!important' is perhaps the best solution. It seems to work well in my own test gallery so I hope it works for you, too.)

For reference, the Search Engine Optimization support section can be found here.

When you create a gallery with JuiceboxBuilder-Pro, select the 'Add SEO Content' checkbox in the 'Customize -> Sharing' section and SEO code will be generated. The SEO code will be included in the gallery's 'index.html' file (which can be used to view the gallery on a page of its own) but it will also be presented in the 'Get Embed Code' window on JuiceboxBuilder-Pro's 'Publish' tab. As long as you follow the regular embedding instructions here you can just copy and paste the entire embedding code into your web page and all should be fine.

However, things are complicated slightly with your own setup. Not only do you use a baseUrl (which would mean that you would need to modify the paths to the images in the SEO code as JuiceboxBuilder-Pro has no knowledge of your custom gallery structure when generating the SEO code) but you also switch between multiple galleries on the same page. You would probably need to merge the SEO code from your multiple galleries (making sure that the paths to the images are correct for each gallery) and manually insert it into your web page (inside the 'juicebox-container' <div> within <noscript> ... </noscript> tags, which is how JuiceboxBuilder-Pro presents the SEO code).

Try creating a sample gallery with JuiceboxBuilder-Pro (with the 'Add SEO Content' checkbox selected) and check the 'Get Embed Code' window on the 'Publish' tab to see the format that JuiceboxBuilder-Pro uses for the SEO code if you plan to implement it manually for your own web page.

Placing the SEO code (<img> tags) inside <noscript> ... </noscript> tags is not hiding the images (so Google should not penalize your site for this). It is simply telling the browser that this is what should be displayed if JavaScript is disabled. Not only is this a method of adding the SEO code to your web page, it also ensures that your gallery images will still be seen even if JavaScript is disabled in the browser.

You're welcome!

Drag and drop the gallery page name onto the gallery index page name.
For example, click and hold the text 'Land', drag it onto the text 'Galleries' (make sure the small arrow is directly to the left of the text 'Galleries', not above or below it) and release the mouse click. (Then click 'Save' and 'Publish'.)

No problem! I'm glad my suggestion worked. Thanks for letting me know.

I've glad that you've been able to resolve your problem.
Thank you very much for letting me know.

Paths in WordPress pages are often absolute but they are usually generated dynamically when the page is displayed.
As you are aware, any hard-coded absolute paths will certainly cause problems if a WordPress site is moved.

The Juicebox plugin for WordPress is called WP-Juicebox and, if installed, it will be listed on the 'Plugins' page in the WordPress admin section.

As far as I am aware, there are no official themes which contain Juicebox so if Juicebox is somehow built into a theme, someone has been very creative!

If WP-Juicebox is not installed, then it is likely that individual Juicebox galleries have been embedded manually into pages or posts.
Each gallery consists of a 'jbcore' folder (containing the Juicebox core files), a 'config.xml' file (containing the gallery's image data and configuration options) and 'images' and 'thumbs' folders. This should give you something to search for on your server.
In addition to the files required for a Juicebox gallery, there will be some embedding code (in the body of the page or post containing the gallery) which will look something like this:

<!--START JUICEBOX EMBED-->
<script src="my_gallery_folder/jbcore/juicebox.js"></script>
<script>
    new juicebox({
        baseUrl: 'my_gallery_folder/',
        configUrl: 'config.xml',
        containerId: 'juicebox-container',
        galleryWidth: '800',
        galleryHeight: '600',
        backgroundColor: '#222222'
    });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

If you find a Juicebox gallery that does not work, then it is certainly possible that the paths in the embedding code are pointing to the wrong places.
For each web page containing a gallery (or galleries), there will always be a path pointing towards the 'juicebox.js' file (inside the 'jbcore' folder).
Depending on the structure of the gallery, there may (or may not) be additional paths in the embedding code as follows:
(1) A configUrl path pointing towards a specific configuration file.
(2) A baseUrl path, pointing towards a specific gallery folder (please see here for details).

If there is any way for you to let me see the site (or at least a dysfunctional Juicebox gallery page), I should hopefully be able to help you further. Thank you.

The Splash Page was designed to be a placeholder for the gallery in Small Screen Mode (essentially an image link with some information) where the gallery may be too small to be useable (on small screen devices) if it is embedded into a web page. When the Splash Page is clicked (or tapped), the gallery is expanded to give the images as much room to be displayed as possible.

You can still use the Splash Page in Large Screen Mode if you like (by setting showSplashPage="ALWAYS") but the Splash Page's functionality will remain the same.

There is a little more information about the Splash Page in the Screen Modes section of the Gallery Tour.

There is no way to override how the Splash Page functions in a Juicebox gallery and it sounds like you might need to create your own custom version of the Splash Page in your web page and load your gallery in its place when it is clicked.
This would certainly be possible but knowledge of HTML, CSS and JavaScript will likely be required (and it would be much easier to work with the available configuration options to reach a compromise).

You're welcome!
I'm glad you've been able to implement one of my suggestions into your gallery.
Thank you for letting me know.

That sounds correct. The module's documentation (Step #3 on this web page) states that you should copy the entire contents of the 'jbcore' folder to your /sites/all/libraries/juicebox/ directory. You should not need to find the font files specifically, though: just upload the entire contents of the 'jbcore' folder to your /sites/all/libraries/juicebox/ directory, keeping the 'jbcore' folder structure intact, and the font files should be uploaded (along with all the other resource files that Juicebox needs) to the correct location on your web server.

The problem is likely to be caused by one of the following:

(1) Please double-check that the font files are present in the correct location on your web server. Even if you find that they are where they should be, try re-uploading them in case something happened during the initial upload which has somehow resulted in corrupt files.

(2) A browser setting or extension might be causing the problem. Try viewing your gallery in a different browser (Edge, Firefox, Internet Explorer 11, Opera, Safari) to see if this makes a difference. If the icons appear OK in a different browser, then try temporarily disabling all extensions in your Chrome browser to see if this helps.

(3) Check that there are no global CSS font rules on your web page which might be setting a custom font for all elements which is overriding Juicebox's own icon font.

(4) A further cause of your problem might be incorrect or missing MIME types for the font files on your web server.
If this is the case, then you may have to contact your web host to ask if they can add the font file types (.eot, .svg, .ttf, .woff) to the list of known MIME types (so that browsers know what to do with them).

If you continue to experience difficulties, I'd be happy to help further but I'd really need to see the problem live on your web server (to at least try to determine whether the problem is server-side or client-side) but I notice that your gallery is currently password protected.
I hope that my notes above point you in the right direction but if you need any further assistance and are happy for me to view your gallery, please let me know and I'll send you an email where you can send me your web page's login details.
Thank you.

It sounds like you are using the Splash Page in Large Screen Mode. When the Splash Page is clicked, the gallery expands using the useFullscreenExpand and expandInNewPage values.

Make sure you set screenMode="AUTO" (in JuiceboxBuilder-Pro's 'Customize -> General' section) and showSplashPage="AUTO" ('Customize -> Splash Page') and the Splash Page will not be used when the gallery is displayed in Large Screen Mode. A visitor to your web site will then be able to expand the gallery by clicking the Expand Button on the Button Bar (as long as you set showExpandButton="TRUE" and do not set buttonBarPosition="NONE").

If you continue to experience difficulties, please post back with the URL to your gallery so that I can take a look at its configuration options and hopefully help further.
