Go to cPanel, phpMyAdmin and in the WHM database, see the bannedips table or something like that and delete/drop when you see yours and try again.
Do you have access to your own cPanel or a control panel?where in whm exactly? can somebody please explain it? i am newbie. my dedi seller dont answer, he is very lazy, how can i do it myself?
Okay, if you like using a proxy site to access your own WHM then it's fine lolz.
