I made a mistake and accidentally changed the front page URL setting in my wordpress admin. Now I can't access my wp admin page and the blog index page is all messed up. I don't know what to do to fix this since i'm new to word press. I do have a backup on the entire domain and php files from just before the mess up. Can I restore these php backups or would I need to do something in my database? Any help would be greatly appreciated. Thank you
