Hi,
Login Unsuccessful
after removing all whitelist
cannot access control panel anymore
Most likely there is no connection to mysql.
If this is the case, when it says "Login unsuccessful" then it means that it cannot connect to mysql. Thus, you need to reset the mysql password. The do:
sh /script/fix-program-mysql PASSWORD
sh /script/reset-mysql-root-password PASSWORD
sh /script/resetpassword master PASSWORD
