After the failure of the database there is a problem with logging on to the Customer & Business Manager. When I'm logged on to Plesk Panleu and move on to the Customer & Business Manager, I get an error:
Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1' for key 'session_active'
Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1' for key 'session_active'
