I just followed the steps for making a multi-site network: added the code to wp-config.php, and then again to wp-config.php and made an .htaccess file. All cool.
I then went to click a link on my website, and it notified me of an internal error.
Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request....Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request. Apache Server at bennotkin.com Port 80
Frightened, I went to remove the multisite functionality, and deleted the code from the wp-config file, and the entire .htacess file, but to no avail. What do I do? Ideally I could go forward with the multisite network, but I'd be happy even just to make my links work again.
