U4-2293 - Error creating in fields in backoffice: There is already an open DataReader associated with this Command which must be closed first.

Duplicates: U4-2172

I'm getting this error any time I try to create a field in any of my Document Types. I've been working with the same site for about 4 weeks so this error is a bit of a surprise and hindering any progress.

I suspect it happened when I renamed, deleted, and recreated some existing document types, but that's only an assumption.

Umbraco 6.05, blank install. Packages installed: uComponents.

Update on this. After about 15-20 minutes, things started working as normal. Like something got recycled or something.

Possible solution is to enable MARS: http://stackoverflow.com/questions/6062192/there-is-already-an-open-datareader-associated-with-this-command-which-must-be-c

Haven't read about the implications yet though.
