I installed Toolset Access in order to prevent the Editor role to access posts. When I login as an Editor, I get this:
"There has been a critical error on this website. Please check your site admin email inbox for instructions."
The Admin can login fine though.
I have tried in two browsers and also emptied the cache. Also I tried different frontend and backend URLs, and they all result in a critical error for the Editor user role.
If I deactivate Toolset Access, there is no issue anymore.
