Problems with receiving and sending email

Hi,

I have recently upgraded to 9.307-6 and I am getting the attached error when
I go to Logging and Reporting>Email Protection>Mail Usage

The error string:

Can't use string ("0") as a HASH ref while "strict refs" in use at /wfe/asg/modules/reporting.pm line 501.

After this error the system does not send / receive any email 

Thanks in advance,
