MT - template ampersands & configuration errors

Hi guys,

I’ve been using movabletype for quite some time now, but it stopped working for me. The last thing I tried to do on it was edit my main index template with two consecutive ampersand codes for a non breaking space… I hit “save”… then got taken to the ‘server configuration error’ page. Now, everytime I try to go to mt.cgi, I get that error page.

Does anyone have any idea what happened and how I can fix it?
