Hi,

I need some more information to investigate this further. Can you please paste the rest of the stack trace? There should be a continuation with "Caused by" prefixes that go into the detail of why the Exception evaluating SpringEL expression: "userConf.get('additionalCss')" happened.

Also, which version are you using?

aileftech commented 1 year ago

Since this now refers to relatively very old version, this issue has probably been fixed. I'm closing this for now, but I will examine again in case of new feedbacks.
