404 Error after Changing URL in Settings

[mightyjak 0]

Yeah, I freaked out too. After messing around with the Settings>WordPress address (URL) & Site address (URL), I lost everything and couldn't get back in either. But then I read this: http://codex.wordpress.org/Changing_The_Site_URL#Changing_the_Site_URL I followed these directions and got it back! You'll find them under Edit functions.php. If you have access to the site via FTP, then this method will help you quickly get a site back up and running, if you changed those values incorrectly. 1. FTP to the site, and get a copy of the active theme's functions.php file. You're going to edit it in a simple text editor (like notepad) and upload it back to the site. 2. Add these two lines to the file, immediately after the initial "<?php" line. update_option('siteurl','http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog'); update_option('home','http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog'); Use your own URL instead of example.com, obviously. 3. Upload the file back to your site, in the same location. FileZilla offers a handy "edit file" function to do all of the above rapidly; if you can use that, do so. 4. Load the login or admin page a couple of times. The site should come back up. 5. Repeat the above steps, but remove those lines. IMPORTANT: Do NOT leave those lines in there. Remove them immediately after the site is up and running again. If there is no functions.php file in the theme: Create a new text file called "functions.php". Edit it with notepad, and add this text to it, using your own URL instead of example.com: <?php update_option('siteurl','http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog'); update_option('home','http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog''>http://example.com/blog'); Upload that to your theme directory, then proceed as stated above. Remove the file afterwards.
