not Seeing manually installed plugins

Hi All i have plex installed on my ubuntu server 14.04
ive changed the default user to my user account due to some of the media being in the home directory

when i manually install plugins to the Application support plugins folder, they dont appear even after restart

ive given my users acess to the folder with chown -r user:plex /folder
my user is also part of the plex group
still nothing.

i even temporarily set the folder to 777 still nothing.

im able to view and change files in the folder via ssh as my user so plex should be able to see it?

using current plex pass version.

Thanks
