Account Settings not accessible in Stirling PDF

[jorrg]

I have an interesting case:
If I install Stirling-PDF on Cloudron - then go onto:

Settings > Account Settings

I get the issue shown in the screenshot above: "Error: 999 None".

The logs say:

INFO s.s.p.s.f.UserAuthenticationFilter - Invalidating session for disabled or non-existent user: (myusername)

Interstingly, seems to be related to the Cloudron I run this on. I tried on a fresh install, and didn't have any issues. I have another Cloudron that is about 6 months old, there the issue appears.

Any ideas what could be the root cause? For now, I will try updating the cloudrons.

I think I found the issue - to be validated!

My cloudron admin account had only two characters. By creating a second account, with more characters, I was able to access the admin settings.
