Installing Django 1.7.7 successfully and then tried to access mydomain.com/admin got to a 500 error page.
Apache error log shows:

It may not be related to the issue but Install script has Django 1.7.7 and its support ended last December. Django 1.8 is a LTS and newest version is 1.9.2 as you can see in below link:
