snorris2 on "500 Server Error - Changing of URL's"

Hi all,

My knowledge of coding, especially with WP, is pretty limited, so please bear with me.

I accidentally attempted to change the WP URL and site URL to the same address, which led to a 500 Internal Server Error. I attempted to go back and remedy it, but no luck - the site and CP are in a server error lock. I can't even access the tools anymore to fix it.

What can I do? If you need more info, please ask and I'll do my best. Like I said, my knowledge for all of this is pretty basic. Thank you.
