Hello,
Built a staging version of my site to test what was making the product image gallery appear on top of the large product image instead of below the image and after some testing of plugins and other themes, it seems as though the culprit is indeed ThemeX.
Turning off all the plugins didn’t seem to matter, only when I changed the theme did the images correct.
(It also seemed to correct the image sizing issue that I occasionally catch on mobile… where the product image stays thumbnail size instead of loading the larger size)
Thoughts?
