Editor Issue

You need to disable all of them, as a conflict can result from one plugin conflicting with another.

I just saw this response. After disabling all the plugins I cannot edit posts, in fact I go to a blank page https://postimg.cc/zVJT9t2T

Does your host keep backup of your site?
As it may be simpler to load a backup to a date before it 'broke'

The backups were not set correctly.

Rebooting the Apache Web Service on my server helped to fix the issue.

Thanks

Glad to hear that
