Hello

I have occured strange error during creation of new report definition.
When I click OK after specifying report name, type, target paths/identities the "Report Definitions" site prints error.
I can make this site usable again by deleting records from database tables "report_definiotion_targets" and "report_definitions". But, when I try to create any new report definition error is the same.



Code:
An unexpected error was encountered.

Please retry the operation, and if the error persists, contact the system administrator.

Any ideas how to resolve this error and finally generate report definitions?
