Hi all,

I'm trying to create new section in EPiServer Mail, but on save I always receive next error:

There is already an open DataReader associated with this Command which must be closed first.

Stack Trace:

Can anyone tell me what's going on? And if it possible to fix this issue...

Any help would be appreciated.

Alex.

Is it possible that you may accidentally replaced the connection string with one without MARS enabled?

MultipleActiveResultSets=True is required, not having that would cause this type of error.

Thank you very much!

I really changed connection string and forgot about MARS.

My respect for the invaluable help.
