When i try to save a slider in Layerslider, i get this message

It seems there is a server issue that prevented LayerSlider from saving your work. Please check LayerSlider -> System Status for potential errors, try to temporarily disable themes/plugins to rule out incompatibility issues or contact your hosting provider to resolve server configuration problems. Your HTTP server thrown the following error: \n\n Forbidden
