Errors

I'm trying to install Vbulletin and I get this error:

Attempting to attach to database...


Parse error: parse error, expecting `','' or `';'' in /3w/webz.cz/t/theckc/forum/admin/db_mysql.php on line 248

Fatal error: Cannot instantiate non-existent class: db_sql_vb in /3w/webz.cz/t/theckc/forum/admin/install.php on line 336

I'm pretty sure all the information in the config.php file is correct because it works for the phpmyadmin

I figured out what it is, kinda. When the ads are moved to the bottom, vbulletin seems to stop working. When the ads are at the top it works fine. Any idea how to solve this?
