when i create a new master list

What is the full Python version? I.e., 2.7.what?

By 'master list' do you mean the 'mailman' list?

How did you create the list?

Does the above error occur upon initially getting the https://www.example.com/mailman/admin/mailman/ page or upon submitting the page with a password?

Hi its Python 2.7.5, yes i meen the masterlist, i create the list via the virtualmin mailman modul.
The https://www.example.com/mailman/admin/mailman/ is not working its
domain:10000/virtualmin-mailman/admin.cgi/mailman

[Mark Sapiro (msapiro)]

I think this is a Virtualmin issue. Have you tried getting help from Virtualmin?

[Lin Hu (linajna)]

yes they write its a mailman issue :-)

[Mark Sapiro (msapiro)]

In the traceback you posted, the exception is raised by cgidata.keys() and is saying that cgidata has no list of keys, not even an empty list. cgidata is the result of cgi.FieldStorage(keep_blank_values=1) where cgi is the Python cgi module.

I think this is the result of the web browser or web server posting the data with a bad Content-Type. Current Mailman (2.1.15 is almost 10 years old) and this issue is a duplicate of https://bugs.launchpad.net/mailman/+bug/1602608 which see, particularly https://bugs.launchpad.net/mailman/+bug/1602608/comments/4
