Https sites doesnt show up properly

[cgprasad]

Hi there
Im using pfsense 2.1 with squid and squidguard. ive made a whitelist and blacklist as per my users,

Im facing a typical problem , such that this site : https://www.tdscpc.gov.in doesn't open properly. Once logged in , the graphics disappear.

Any idea, how to access it smoothly.
I' m using a shallalllist black list and have enabled government , finance and related stuffs.

Thanks
