Question

I added a new tab and when I try to rename the existing (only one) tab from Field Tab to something else, it gives me this error. Can't find error message in the atlassian-jira.log

This is the time that you will need to open a ticket against Atlassian Support. All your info above will speed up the process. They will find the rootcause in no time.

That's the beginning and end of the same java exception. I tried to disable all plugins I just installed, still got error like this:

Are they one and the same error log? It seems to be a plugin? Can you disable that for the meantime?
