I found the issue with broken css.
We are serving certain css and assets like images using https://flocktofedora.net and not https://flocktofedora.org whereas the ssl certificate that we are using is for *.rhcloud.com. Now browsers will throw errors when I'll try to browse https://flocktofedora.org which I can add an exception but since I didn't knew about https://flocktofedora.net, I didn't add any exception for that and it was failing. To fix this issue, we should start serving all the assets from a single domain and probably get a certificate for flocktofedora.org. In the mean time, one can just go to https://flocktofedora.net and add ssl exception.
