Layer Slider Server Error

I keep getting this error when trying to add and save new slides. I’ve updated my theme, and latest wordpress version.

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 Internal Server Error”
