Plex Server Stopped adding newly added media

Starting on Sunday (which I had just upgraded to the newest public plex media server) any show or movie which I add is not being added to Plex. I upgraded to the newest plex pass media server (1.12.2.4929) and the files still will not show up. I have not changed any settings and have tried renaming the files in every single way that I could think that works even copying the previous episodes file naming structure and just changing the episode number and the files still will not show up. I can tell it notices the changes because as soon as I change the file name it scans the folder the file is in but the file is not added to PMS. I have made sure that plex has permission for the folders containing the files and every other piece of advice I have been able to find that relates to my problem but none have worked. Any help would be appreciated. Thanks
