Impossible to create a new photolibrary

[D33FE210B718]

I can not create a photo library, the frontend says "Your changes could not be saved." It is not a permission error, I set the entire folder to 777 for testing. Also the shared folder is accessible by other librarys.

I tried a bit with postman but still no luck

If using the agent value from this Unable to create / add Photo Library “Your changes could not be saved” post

scanner=com.plexapp.agents.none

the error 'agent' is missing or invalid disappears but 'language' is invalid stays no matter the value.

Can you post your server logs?

I already added the relevant logs in my post.

After several reboots, I just reinstalled the plex media server on my shield and now it works. I can create a photo library. Also the postman request now works

Only difference I noticed on the webpage is the language dropdown appeared, before it did not display when choosing a photo library. But this does not explain why the api request did not work either. So I am guessing it was some sort of runtime/database error.
