:htaccess help!

I am working on setting up TWiki on my domain.
In the process i managed to transfer empty htaccess files to my domain root. Now my site dont work any more, i get the 500 internal server error message.

Can i write anything to my htaccess file to make the site back up ?


I found a post in this section telling me to display hidden files in my ftp program. Doing that i deleted the htaccess files wici is at least a way of making my web page working until i manage the files.
