I disabled Multisite. Deleted all wp-config lines, updated .htaccess with the default code and deleted all MySQL entries.
Now my homepage - pitch.pt - keeps redirecting to pitch.pt/home2.
All other pages, posts and dashboard are working fine.
I went on phpMyAdmin and found that on wp_options
the URLs were set to home2, but already fixed that.
I've disabled plugins, verified wp-config and updated permalinks.
