I have manually installed latest pms on the NAS but I am not able to add any libraries to Plex. The "Next" button in the add libraries tab is "grayed out" even when I select folder etc. I drilled down to even trying to import individual albums with no luck getting access to it.
I finally got the prompt "There was an unexpected error loading libraries" please visit forums.
I also am running into the issue where the "server settings" are unavailable. I have tried through both local access with the browser to 192.... and through the plex website login.
