Messed up when Moving Site To New Directory

Hi I need help I messed something up and now can’t seem to fix it.

I was trying to follow instructions for Giving WordPress It’s Own Directory: Using a pre-existing subdirectory install. I had the website running from a subdirectory and wanted to point the root at it.

I copied the .htaccess file as directed and the index.php file but what I think I did wrong was when changing the URI in the admin panel settings I also changed the WordPress address to the root address. I think I was meant to leave that. Now it wont let me log into the admin to change it. I’ve even tried adding the wp-login.php file:

//FIXME: do comment/remove these hack lines. (once the database is updated)
update_option(‘siteurl’, ‘http://your.domain.name/the/path’ );
update_option(‘home’, ‘http://your.domain.name/the/path’ );

But nothing is working.

Any suggestions?

Thanks heaps!!!
