My problem is, all I can get on my television with the Plex App is "No Library Sections". I've been fighting with this for almost a week.
I moved Plex from one computer to another following the instructions at "https://support.plex.tv/hc/en-us/articles/201370363-Move-an-Install-to-Another-System".
Everything loaded up perfectly on my Plex Media Server and on the Plex Web App, and my family and I even watched a movie for 45 minutes at which time we got "this video is not available" and the "no ibrary sections" and that is what we've been getting for 5 days now.
Eventually, I just wiped out Plex completely and decided to try installing Plex like new and just re-uploading everything (I tried uploading a small library).
Everything loaded up perfectly on my Plex Media Server and on the Plex Web App, but when I turn on the television and select the Plex App I get "No Library Sections".
I have an old television that has composite audio/video ports, and a Roku1. It worked fine for 20 months and suddenly nothing I do will get it to work.When I try to play my Plex App I get a message that there are no Library Sections
My Operating System is Windows 10; my version of Plex was 1.2.3.2914. I uninstalled that and went back as far as 0.9.1603.1840 because I was told that the latest version of Plex for Roku would not work with the composite audio/video ports. That didn't work either.
I've done so much stuff over the past few days the I can't even remember everything I've done.
I appreciate the help everyon offered (If you suggested it, I did it). I'm hoping someone with enough knowledge of Plex can tell me what I can do to fix this problem.
