I'm trying to remove /blog/ from my permalinks which is something I had done easily before by going into the site settings in the network admin but for some reason it is no longer working.
When I hit update I get a 404. It's going to this page /wp-admin/network/site-settings.php?action=update-site and no changes are being saved.
Anyone know what could be causing this? Or have any alternative way of removing /blog/?
