Weird Problem Communit Builder Tab

Ok I have found the issue. For some reason I had following code in database plugin tables:

{"menuFormat":"menuBar","statusFormat":"menuList"}

It seems that this has not been cleared out correctly on upgrading.

Strange, that's supposed to be there but it's in the wrong format. We don't json encode our param columns. It should be as follows.

menuFormat=menuBar
statusFormat=menuList

Still don't see how this would cause the credits menu item to display even after disabling it.

I found this out be doing a clean install with Joomla 2.5.16 and CB 1.9. The clean install did not have

menuFormat=menuBar
statusFormat=menuList

in the database after removing the credits menu item.
So should I enter this manually or is it not required?

It won't matter, it'll just use defaults within PHP when trying to pull the parameter. Just leave it alone and it should work fine. If you want it there then edit the CB Menu plugin and save it once and it'll add those parameters. Those two parameters have absolutely nothing to do with the Community menu item so I've no idea why it'd cause you any problems.
