Mailman though working, is throwing 500 Internal server errors in reply to perfectly normal requests such as a new subscriber trying to access their account page and even the main mailing list page at http://greenhithe.org.uk/mailman/listinfo/mncmail_greenhithe.org.uk It's odd but I can't see how to fix it. Can anybody suggest a solution please? Thanks Paul greenhithe.org.uk
