litespeed cache issue

[Chadi]

I just installed Litespeed on my server using this plugin:
http://www.litespeedtech.com/support...auto-installer

I'm running vBulletin 4 and I realized when new content is posted such as a new post or thread, it'll refresh the page but I have to manually F5 refresh to see my new post on the page. This was not the case prior to installing Litespeed. How can I fix this? I'm not running vbseo either but dbseo.

.htaccess for vbulletin
