I keep getting the "There was an unexpected error loading the dashboard" message when I open Plex, and keep getting "There was an unexpected error loading this library" when I try to open one of my libraries. That library is on a HD with a few others, and all of the others open and work fine. I've tried to repair the database and had no issues, tried optimizing, tried analyzing, and have had no luck in fixing the issue.
I am having the exact same issue. And I can’t “Go to” any of my movies all of a sudden. I have to press and hold done on the movie and select “Play Movie”. HELP!!
Im having the same issue as well. Started after the latest PMS update it seems.
