For a while now we have been seeing the ocassional mailman error such as this below. Servers running Cpanel
Bug in Mailman version 2.1.13
We’re sorry, we hit a bug!
Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs.
Heres a quick and simple fix.
Issue the command – find /usr/local/cpanel/3rdparty/mailman/cgi-bin -type f ! -perm 2755 ! -name create -exec chmod -vv 2755 ‘{}’ \;
This command, using “find” will find and apply the correct permissions of 2755 excluding files named “create”
