Thanks for the positive comments and for your question. Thanks as well for the link to your site and the examples there.
I had a look at your site, and it looks like you are using the Photoswipe gallery plugin to compose your galleries; is that right?
I do not see any evidence of HTML markup or CSS styles on the page; just a Photoswipe gallery. You may be using MLA with the mla_alt_shortcode
parameter to select the images and then hand off control to Photoswipe to compose the gallery; is that right?
In this scenario, MLA does not emit any markup or styles and it does not play any role in the gallery display. You will have to look at Photoswipe and your theme to determine the cause. Here is an earlier topic along similar lines that may give you some clues:
Fixed height and Auto width on images displayed via mla_gallery
I did notice that when your page loads it throws a couple of JavaScript errors:
SCRIPT5009: ‘jQuery’ is undefined
File: Galleries, Line 1, Column: 27220
SCRIPT5009: ‘imagesLoaded’ is undefined
File: Galleries, Line 1, Column: 23870
The errors look like they are associated with something called “ajaxRevslider”; does that make sense? Once the error happens JavaScript is usually disabled. That may account for the incomplete loading of the gallery and the display of the image file when you click on a gallery thumbnail.
You wrote “I think that it may have something to do with my cache plugins“. Have you tried disabling those plugins to see if it affects the problem?
I am marking this topic resolved simply because I can see no evidence that MLA is involved or not functioning as it should. I hope you can find and resolve the problem by working with other theme and plugin authors. If you get any additional information that suggests MLA can help, let me know. Thanks for your interest in the plugin.
