Hi, unfortunately, this issue started before there was a single plugin installed. But to ensure I covered my bases and I tested it, I have deactivated all plugins and the problem remains.

I have also done things like clearing Cache, increasing memory to 128 on the web server. Everything that has been recommended in other Forum suggestions. And no change.

At one point, I started from scratch fully uninstalling wordpress from the host and reinstalling, not using a back up but starting from the beginning and it ran smoothly until quite literally it suddenly stopped loading the edit window.

Kind regards
Kendra
