html validator 500 Internal Server Error

Hi
I'm trying to validate my website www.softpilar.com

But I keep on getting this result: 500 Internal Server Error

http://validator.w3.org/check?uri=http://www.softpilar.com/&charset=(detect+automatically)&doctype=Inline&group=0&ss=1&verbose=1

I checked with my web hotel provider. The told me all the dns settings are
OK. So I hope you can help me.

Regards Bilal
