I helped another user out with this a little while ago. Below are the instructions to fix it.
I havent made this part of the package as you are only the second person to have the problem. On a side note though, following these steps will speed up everyones article by a couple of nanoseconds.
Edit showthread and find this:
after, add
PHP Code:
'GAS_showthread','GAS_comment_pb','GAS_article_pb',
save and close
edit forumdisplay and find:
PHP Code:
'FORUMDISPLAY',
after, add:
PHP Code:
'GAS_forumdisplay',
save and close
edit printthread.php and find:
After, add:
PHP Code:
'GAS_printthreadbit',
save and close
then replace your functions_geekarticles with the one attached.
