Thanks for the report.

Which version of Umbraco are you using? Perhaps there is some difference in logging in the older versions of Umbraco.

Also, is there a stack trace associated with this error? That would typically be in the Umbraco log file in App_Data/Logs.

No Stack trace but here's the full content of the error message:

Any luck, Amir?
