There was a discussion here a while ago that the style option of the Web Page can block out the Drop Down Box.Tried all versions - no drop down appears.
At the very bottom of the the page on the full web site (not the Mobile Version) in the lower left side you should see a small window just above the Eccie Logo.
Mine is set on Eccie HD and can see the drop downs mentioned.
Try selecting a different "style" of display for the Forums and see if that will resolve the issue for you. Originally Posted by biomed1
