What plugins do you have??
I have a few. Users browsing forum, users browsing threads, easy affiliate, ads after first post, Profile comments, skype bb, profile buddies, Refferal in profile, miss you email, adsense ads on forum display, dynamic meta, Board messages, Auto media.
I have a feeling it's the profile comments one, can you deactivate it?? Shouldn't lose any data from it.
I did that and still showing 0 views
I disabled ALL my plugins and then again and they are now working.
Try re-enabling each one one by one to see which one did it, then report it to the creator.
