Dashboard - Internal server error 500

Hi. After Cerber worked fine yesterday, suddently I can’t use the Cerber Dashboard anymore. There are no updates to wp nor cerber. Both at newest versions.

I still have access to Traffic Inspector and can see the following “HTTP 500 Internal Server Error” each time I click on WP Cerber in the menu. It also happens intermittently when I click on a page (paging) say page 3. Sometimes that page shows up other times I get a 500 error.

When such a software error occurs, WordPress sends an email with detailed information. Did you receive any?
