403 error even after removing the plugin


New Member

I'm using wordpress and I get a 403 error (screenshot attached) when I try to save a draft or publish a post.
The strange thing is, I keep getting it even after disabling LiteSpeed plugin or even removing it.
I uploaded to my server the 403 and 500 HTML pages you suggested in a different post but it didn't help.
I also cleared my cache and cookies, tried incognito and a different browser - nothing helped.
The server logs don't show any problems.
Anybody can help?
