Not displaying threads

[Express]

I recently installed vBSEO. When I change the general settings my VBulletin Forum fails to work as expected. The POSTS are displayed but when a post is clicked the thread doesn't get displayed. I get a PAGE NOT FOUND error and my URL looks like this www.vbseo.com/f77/error-installing-ioncube-version-14641/

Which setting should I change in vBSEO to enable the forum to display the threads again?

Hello,

make sure that you uploaded vBSEO's .htaccess file.

That worked. Thanks
