a vbulletin virus?
 

i have a very big problem:

i havfe a forum where me and a friend are administrators..

my friend told me that yesterday..he saw a download button at the admin panel, (to update vbulletin version), he clicked that button and then...the forum doesnt work well...

for example..nobody can make a post because the sistem display a message wich says "you need to write more caracters"..but i wrote a few!

i dont know..vbulletin always must be updated by download it at the official page...i´ve never seen an advertisement saying "update your vbulletin version!" and a download button :s

can anybody view my forum and search for a virus or a vbulletin bug?

please help me...is a big forum with lot of users...but the forum is not operative because this error :(:(:(:(:(

thank you very much :D
