Database login cookie did not match your login cookie

Guys,

I’m back with a question, perhaps one of you have gone thru this.
I’m doing some tests with Open LiteSpeed and I moved my site from LiteSpeed Enterprise to it.

I can’t make the cache plugin work anymore, I keep getting this message at the top of WP dashboard:
Database login cookie did not match your login cookie

I checked the .htaccess file and I can see the lsvary cookie there, with the proper name I set on it. I did restart LSWS, logged out and back in, but it doesn’t change. Always get the same error message on wp-admin dashboard.

I also notice the cache is not really working. Guest visitors on the site never get a cache. when observing the headers, sometimes I see the cache miss there, sometimes nothing at all. Never a cache hit.

I also tried removing the plugin and re-installing it but no luck.

Any ideas?

Thanks!
