Hello EdX team,

Installed Open edX platform on ubuntu 14.04 with dogwood.3 release.

When I click on Discussion tab of any course on Open edX platform, It is showing 500 error .

Here are the logs from lms/edx.log and nginx

sudo tail -f /edx/var/log/edx.log

I created forum.sock manually, given www-data ownership permissions and tried still the problem exist.

Please help in how to enable enable forum (discussion) page for every course.
