Why Does it do this?

If you don't know where they are, you should ask your host. It just seems the perhaps there is an error that is stopping the rest of the page from printing out and that is may be in the error_logs. Or, as the other poster said, maybe you have a condition around it that isn't working.

Try viewing the page in a default vb style and see if you still have the same problem:
Create a new style with no parent:
Styles & Templates > Style Manager > Add New Style :
Parent Style: No Parent Style
Title: Default vBulletin
Allow User Selection: Yes
Save
Then browse the site using that totally default vbulletin style - do you still have the same problem?
