My User Macro's fails after upgrading to Confluence 5.2 (from a 5.1.x).
All macro's are marked as "There are user macros without any metadata configured in their template. They have been highlighted below. For these macros to be available for use in content they require parameter information. "
Which are not correct - all worked previously. And they all render correct in the UI
Editing a macro on a page gives a similar information regarding "No Macro Data"
