server error

Hello!

I just checked amxbans, and your admin should still be activated, as it hasn't been removed or altered with.
In terms of your password, I believe you can change your 'setinfo' details at any given moment in the shop's settings.
Go to shop > settings > type in the password that you desire in the 'Password (setinfo _pw)' that is located next to your nickname. The changes should apply after the map change.
