Root PHP files not getting executed

[cool_dude_99]

I have associated my domain checkbulkpagerank.com using add-on domains few days back
It was working fine till tomorrow BUT Today the url checkbulkpagerank.com Is not opening ..Rather than executing the php files on the server its providing them for download WHEREAS the system is working fine for the files which are not on the root EXAMPLE the url : http://checkbulkpagerank.com/mass_pagerank/ is working fine.

I will be very thankful if mods can see to this matter

Thanks
Edit:
Well don know what's wrong..BUT Its running OK on internet explorer :| BUT Giving problem on Firefox 2.0.0.14

I can access with no problems to: http://checkbulkpagerank.com/ , and I don't get a download page.
Clear your cache & temp files, make a flush of your DNS and try again.

Seems like the problem is with the DNS of BSNL ( India's leading ISP) because all BSNL users are experiencing the same problem where as other's don have any problem

Just give 24-48hs and it should get fixed. If the problem still persists feel free to re-open this thread.
