I suddenly lost the ability to connect or re-connect to Apache sites. The sites still work correctly, either in connected or not connected modes.
Particularly, I can no longer connect to PHPMyAdmin - it stays on the login page without any error. There are no error in logs, the connection attempts do not even appear in the logs. It seems that Apache - MySQL do not intereract for login - though once connected, it works mostly fine.
Thank for help, I am totally stuck
