Drop down problems from Photopost directory
 

My vbulletin has the add ons Photpost and reviewpost -

The blog drop down works fine from the main vbulletin directory but from the photopost directory it goes into a page not found
See
Main Index - Italy pictures
( it goes into the photopost directory looking for blog.php )
What is the best way to fix this ??

I asked on the vbulletin forum ( which to me seemed a more appropiate place to ask ) but they send me to this forum

Your dropdown menu's that I see work fine on Photopost?
