Can't save the new category

HI,
After fixing new HD to my Netgear NAS 626X and installing Plex Server (new) from start
I don’t know why I can’t create category it says
( Your changes could not be saved. )

here is the image :

its first time this happening, I had same installation on other NAS but worked fine

Please try restarting PMS. We’ve got some reports of that not working after a new install, but works fine after a restart.

Yes you right it worked now

thanks

one more thing if you don’t mind

what this claim thing is for exactly ?

as I have two Plex server on same ID

and my Internet Provider doesnt allow me to connect to my Plex outside my house

so is it important ?

You can have multiple Plex Media Servers associated with your account.

The server must be claimed if you want to use any Plex Pass features - intro & credit detection, hardware accelerated transcoding, etc.

it worked after restarting

but why now it doesnt bring the movie data to the files as before
I can do it manually but it wasn’t like that before … I’m logged in and everything

any suggestions

here as you can see all movies metadata are not loaded to my media
had to do some of them manually !

it didn’t bring al metadata by itself I had to choose
( Refresh all metadata ) to bring them all

so worked this way this time
