Blank page

#1
We have the lite speed web server licensed and we use the prestashop litespeed as well.
We have a problem that out of the blue our website, gets a complete blank page, it doesn´t return any errors, just a blank page.
Sometimes it comes back to life a few minutes later, but most of the time it doesn´t come back and we have to reset our server in plesk or flush lite speed cache and it works.

If we take off lite speed cache it doesn´t happen

Anyone can help us?

I put in google gemini and returned this:

"This error indicates that LiteSpeed is blocking access to your site's root directory (/) and, interestingly, to the custom error folder as well. This is a server-level permissions issue or a misconfiguration within the .htaccess file."

"The logs show an ACL Access Denied error for both the root context and the /error_docs/ directory."
