Please talk to your host/follow this article https://wpadvancedads.com/finding-errors-with-wp_debug/ (just found off google) to gather more information as to what may be happening.

It sounds like a fatal crash somewhere.

Once I have that information I can see if a resolution can be made.

Thanks 🙂

So you have no issues with my plugin?

I would disable my plugin(s) then and see if you still have issues. If you do then its wp-rocket likely.

thanks.
