I have tried to create a multisite for the first time and have several sites I want to run off of a single WP install.
I decided when I would create the multisite to place it in a subfolder called 'WP'. If I had know that somain mapping would not work this way I would not have made it. Is it easy to migrate out of this wp folder? Do I just move everything out of the WP folder and then edit the wp-config.php and .htaccess files to reflect the change?
Then after this I can use domain mapping?
