Vbulletin 3.7.3 problem

[Emma_vbulletin3_import22545]

Hello there,

I do hope someone can help me please but i am having a problem with my forum.

I've tried google etc but have come back with nothing.

Your help would be truly appreciated.

Warning: Unknown(./includes/vba_global_error.php): failed to open stream: No such file or directory in [path]/includes/functions.php(2851) : eval()'d code on line 21

Fatal error: (null)() [function.require]: Failed opening required './includes/vba_global_error.php' (include_path='.:/usr/share/pear') in /home/sites/mywebsite/public_html/community/includes/functions.php(2851) : eval()'d code on line 21

I had just recently installed the software from here.
