==== "www" instead of "apache =====
+
But if you are not running the contribs compiled version, Mailman's management interface shows up with a CGI error message. It complains about group mismatch error between "www" and "apache". Login as root and apply the following workaround, which was suggested in [[bugzilla:6425]]:
+
+
id -u apache # should yield 48
+
id -u www # should yield 102
+
usermod -u 102 -o apache # makes apache user and www user identical
+
groupmod -g 102 -o apache # make apache group and www group identical
