Class 'vB_Template' not found
 

I'm getting this error:

Fatal error: Class 'vB_Template' not found in /home/userx/public_html/album.php(1578) : eval()'d code on line 19

I'm running 3.8.5 and the latest Photopost - I tried replacing all the Photopost files yesterday, though when I tried to install it, it said I had the latest version anyway.

Thanks in advance.

Are you sure you have vbgallery? because the file album.php does not exist in vbgallery and there is nowhere it comes even close of album.php in plugins..
