[Mailman-Users] Installing Mailman on a Debian system with Apache 2.4.2, CGI error!

[Jayson Smith]

Hello,

Okay, now I feel like a total dummy. No, Suexec wasn't enabled as far as 
I can tell. Yes, the CGI scripts are owned by mailman:mailman. Yes, the 
permissions are correct. So what was the problem, you ask.

It seems that by default, Debian's Apache install doesn't enable the CGI 
module. Somehow, it sort of works better if you enable CGI. It works 
better if you plug it in.

Head…desk. I'd spent hours trying to troubleshoot this! Sometimes the 
most obvious things escape the best of us.

Thanks anyway.

Jayson
