When I checked my sites yesterday at 10 PM, everything was ok.
But when I checked it now I found that there are several problems.
One of my site http://blog.delivi.info/ returns a "HTTP 500 Internal Server Error" and my other site http://ms.delivi.info/ could not connect to the database. Please look into this and solve the problems at the earliest.
I didnt cahnge any settings or configuration so the problem is only in ur side.
