Hello Catholicans,
Have you changed wp-admin access? We can’t log in anymore.
These questions you need to pass to your hosting provider, they will be able to check the situation with memory more deeply and help you.
Compare plugins on both sites, maybe one of 3rd party plugin requires too much memory and cause the problem.
Kind Regards,
8theme team
