Downgrading Plex Media Server

Hey all,

I've installed OMV Extra and Plex Media Server. Everything peachy except for the subtitles stops working after watching movies/tv shows for few minutes.

I've done some research and it appears that the issue with subtitles not working appeared after PMS was updated to 1.9.x. The current fix is to downgrade PMS to 1.8.x.

How can I do this? I'm not linux savvy

I also have the same version but the subtitles sometimes disappear after a few minute of playing the video.

I noticed this only happens if it's not a MKV video.

I might just end up converting all of the videos into MKV with subtitles burnt in
