Hello,
One of my clients uses a staging website to build new pages, we then save those as templates, download them and upload to the live website. We’ve not done this in a while, but it had previously worked successfully.
When my client tried this recently they got the red “uh oh” error, saying the formatting of the file was incorrect. I checked the page to ensure there were no legacy / classic items and even tried exporting the page section by section in case the tco file was too large. But no luck.
I tried to put Wordfence into learning mode in case it was the firewall. I also tried white listing my IP in Wordfence to bypass all security features, in case Wordfence was blocking unknown file types - but still nothing.
Any idea what this might be? I can’t give you access to the live site unfortunately as my client is big on security, but I can give you access to the staging version if you want to try it out there.
Thanks for your help and support.
