For all those using SourceGuardian in WHM/cPanel there has been an update tonight to edge/current release trees. Source Guardian has released new loaders (the 4.x series). These are now installed with sourceguardian in the tweak settings page. The older series (1.x 2.x) are now under oldsourceguardian in the tweak settings page. If you wish to use the old loaders you must change this.
