508 resource limit is reached and blank admin

Hi there,

I just installed and configured the Defender plugin on one of the sites I manage.

After updating the SALT keys the Defender usually asks to re-login and after that I end up with the following error: 508 resource limit is reached. After that I was able to get to the login page, but once I logged in, I got a blank page instead of the WP Dashboard.

Can you please advice?
