Twitter Login disappear

edit

Initially I had the twitter login option. I was editing util.py on deps/django_authopoenid, basically I was adding another key to data dictionary. All I did was copy the google and change the name while changing the image file. After reloading apache I endup getting error so I did full revert from my bitbucket and re-deploy the application again. Now I can't seeps to get the twitter logn along with few other major login images to show up. I only have Google, Yahoo, OpenId and AOL. I saw a similar question but answer was server time. My server time is up to date.
