Ok, I downgraded PHO to 7.4
I have done this thing about taking down plugins to the bare bone last time I had an issue with your theme. It turned out there was a CSS causing the problem, but my site was down for several days. I don’t want to go through all this whenever your theme has an issue.
I haven’t done anything unusual to the website. Have you been able to read my last message? That the gallery is showing on previously uploaded products but NOT on the new ones I uploaded? I don’t think that is a Plugin issue since it works on my old products, not the newly uploaded ones.
Can you please take a look? You also have FTP access plus admin access.
