[Mailman-Users] Trouble Subscribing - You must supply a valid email address Error

Hi,

I recently migrated Mailman to another server. One user reported that he went to subscription page to subscribe a mail list, he entered a valid email address , picked a password and hit the Subscribe button, the page returned 'You must supply a valid email address'. I tried to subscribe the list myself and got the same error. I took a look at the error log, and it said "Jun 10 06:21:14 2010 (30782) No such list "_images":".

Do you have any ideas why I got that error? Maybe I missed something during the migration?

I'm running on Mailman 2.1.9.

Please advise. Mary
