I am using Debian 7.1 (wheezy) with mailman and since a few days, the mailman web-interface does not work any more.

The error logged is:

Jul 24 18:34:32 2013 admin(32166): @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

admin(32166): sys.platform    =   linux2

Does anybody has an idea how to solve it?

Thanks in advance for any help!!
