Problem with Plex Music

One day, as I was browsing the Plex collection on my Synology DS1815+ Network Attached Storage, I noticed that my Plex server was not able to find any of my music (although all of the files were there)

The files on my Synology server are all organized under:

/volume1/Media

After trying multiple options, I finally found a working solution, first described here:

1. Synology: Enable telnet/ssh access to the NAS
1. Control Panel/Terminal & SNMP -> Enable Terminal Access
2. Login to Synology using PutTY (terminal program)
1. telnet 192.168.0.101
3. cd /volume1/Media
4. sudo -su root
5. sh4.3#
• find ./Media -type d -exec chmod 755 {} \;
