He's trying but probably is miserably failing.
I suggest you just block the IP in .htaccess

Deny from 64.7.132.147

he still after all my forum i just open a new one and was clean no mods when he went there and still log as anyone he wanted but this time he got a surprise the admincp have htaccess password and is long.

that right there let me know he dont have ftp to server he just use sql injection .
i know vb is solid but maybe he discover a way in not sure.
he also use anonymus proxy .

lol looks like hes trying to hack you using Visual Basic

i wouldnt worry about him if hes trying to do that :p

haha good point. :p

PHP is the only thing you should be worried about (as extension is .php)

if you are using arcade or some hack that's require 777 chmd that is very risky anyone can defaced your website or even can have password of your cpanel. so just check it again
