404 error for alle pages except homepage

Hello,

I’m not sure if this issue is related to Bricks, but I’ll post the question just in case.

Sometimes I only have access to the homepage of a client’s website. For all other pages, I get the following message:

Not Found
The requested URL was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

The problem is temporarily resolved when I set the ‘homepage’ to a different page in the reading settings of WordPress.

What could be the cause of this?

Thanks!
