I'm aware that there are already plenty posts out here about this same error message. However I think I've tried all the options and sadly none of them have resolved the issue. I get this error when clicking Create Pages for the ultimate member plugin. Or when activating some wordpress forums plugin that directly attempts to create the necessary pages.

I tried these things:
– Increase Limits in the php.ini File
– Disabling all plugins except the member plugin.
– Increase Limits in the .htaccess File

My wordpress is installed in a docker container using CasaOS.
