PF has reportedly updated its favicon, but some users still see the old vBulletin icon, likely due to cache issues. Clearing the cache is suggested as a solution, but some users continue to experience problems, particularly with Internet Explorer, which may not adhere to favicon standards. One user mentioned they accidentally overwrote the old favicon and created a new one. After restarting their PC, the new icon appeared for them. Overall, the discussion highlights ongoing confusion and technical issues surrounding the favicon update.
