500 error

[swissmark]

Hello,

My shop has been running perfectly until yesterday. I haven't changed nor touched anything but all of a sudden the frontend shows a 500 Error - Internal Server Error. However, I can still log into the backend.

I have contacted my hosting company. This is their response:
I regret, but as I checked from our side, php and mysql work fine. There is no any problems to run any scripts.
Also I checked server error logs and found that your script cause premature end of script headers: /hsphere/shared/php5/bin/php on the server.

Anyone's having the same problem? What does this mean with the premature script headers?

Any help is highly appreciated.

thanks,

mark

Dou you use REWRITE in .htaccess files?
Try to rename it, or generate it again if you already use them.
