Troubleshooting “There was a problem saving these settings” Plex Server on Raspberry Pi 3
Sometimes Plex server appears to have error “There was a problem saving these settings”. For me, this sounds like a permission problem. Here is a guide to troubleshoot problem. You can also share your ideas about this issue.
If this is a permission problem, then the easy solution here is to use 777 permission
sudo chmod 777 -R /var/lib/plexmediaserver
Check your browser again. If this works then its a permission problem.
You can continue with this settings but it’s not advisable to use 777 permission because it a security problem. But if you don’t care about it then go on.
Changing Plex server folder permission
If you prefer not to continue with 777 then use 770. Its good to use 770 so the owner and the group members can access the files in the folder.
Make sure you add pi as a Plex user
sudo nano /etc/default/plexmediaserver
Change Plex user as pi
Take ownership of the Plex folder where settings are saved
sudo chown -R pi:pi /var/lib/plexmediaserver
Change the folder permission to 770
sudo chmod 770 -R /var/lib/plexmediaserver
Reboot and check your browser
Try other browser
Some said they used different browser in configuring Plex server and it works. Try to use firefox Private browsing (ctrl+shift+p), chrome incognito (ctrl+shift+n) or Internet explorer InPrivate (ctrl+shift+p)
Uninstall Plex media server completely
If the suggestion above don’t work for you, maybe uninstalling it completely and reinstalling it would help. Here the guide:
sudo apt-get purge --auto-remove plexmediaserver
sudo apt-get update
Reinstall Plex media server package
sudo apt-get install -t jessie plexmediaserver
Please leave a comment if you find the solution. Thanks.
