Okay, I have a problem now, when I enabled multiple sites, after configuring .htaccess and wp-config.php, I keep getting “Error establishing database connection”.
I have followed the steps three times, the first time was successful then I realized that I needed to put WordPress into the root directory to have it work properly, I disabled/removed multiple sites from the configuration file and proceeded to follow steps to move the WordPress directory.
The second and third times I tried enabling it, I got the error I described above.
