I've tried clicking on the thread prefix dropdown menu, and nothing appears. No menu at all. This happens in all forum sections. I've disabled all the plugins/addons on my website, and tested with multiple browsers and the problem still remains the same.
I have no idea how this could have happened, since I haven't done anything to my website besides install Xen Media Gallery and remove sonnb's xengallery.
Since this is still an issue when disabling all the plugins on my site, i don't really know where to go from here. I've also tried rebuilding the caches, re-saving the thread prefixes and groups and still no bueno. can someone give me some advice?
