So, It was a Plugin called ‘Feeds for Tiktok’ by bPlugins.
No idea why that changed everything. but it did.
Thank you for your assistance with this matter!
Have deactivated everything and it has fixed the error. Currently reactivating one at a time. It doesn’t seem to be a logical plugin that should have any relevance to product displays. Will post my findings.
the issue is displayed on the links I added. I have run a conflict test, the only one I haven’t deactivated was the storefront powerpack plugins.
