Somethings not right with my page setup. On "new posts" where there used to be the option to go to pages 1 to 10, it's gone. Same on all other sections of the forum, no next page or option to jump to direct pages. Have I done something?
Have you tried the reload arrow in the search box or cmdR and clearing cache history and loading the SD fresh? And of course quitting and restarting both Safari and/or your Mac!
I have noticed that top left of the thread panel I get a "Show only unread" filter indicator which crops up unbidden or requested....there is an x beside out to dismiss it but it seems to return willy nilly as a default....the filter settings are over to the right and may have been hit inadvertently.
I have also noticed that I have ended up "liking" more posts than I intended when I have been swiping through posts with my thumb on the iPhone.
I’m not too sure in that case, if it’s doing it in two separate browsers... I agree with Alantoo try a reboot, then try deleting browser cache from in settings (careful it may delete passwords - make sure you know where you can get a new one!)
