Hi There, I changed the “WordPress Address (URL)” and “Site Address (URL)”.in the settings of my wordpress admin panel. I know, I'm an idiot. 

The website was installed in /public_html/wp but I didn't want them in the extra wp folder, I just wanted them in the public_html folder, so I took off the /wp. Now my site won't load...it tries, but it doesn't seem to work.  

The wordpress help article says I can edit the active theme’s functions.php file with the code: 

update_option('siteurl','http://example.com' );
update_option('home','http://example.com' );

But it doesn't seem to work. (It changes the site to "critical error"). 

I have no idea what to do. My web host doesn't either.
