I will report all as soon as possible, i will be away for four hours more today unfortunately. I have try this night to truncate some table like vbsession on database, but also there is a problem and it return error (the phpmyadmin of the server provider! .... but i do not think it is a problem of misconfiguration of apache server or mysql, i think somebody have hack vBulletin this time ... i think (not sure) at this moment, looking into what i can see right now).

I had try to truncate tables in the vB database as before i had say and the returned error is this (any operation i try to execute on the server phpmyadmin interface):
Quote:
#1142 - DELETE command denied to user 'Sql129...'@'62.149.150.254' for table 'w3_vbsession'

the 62.149.150.254 indicated server for the executed query, isn't the correct server IP.

I will report in four hour more the code i think is bad, contained on some other table like vbexternalcache __DEFINE_LIKE_SHARE__
