I purchased the LayerSlider WP plugin from Envato and somehow when I installed it I authorized automatic updates. I experienced a very unusual problem yesterday that I think is related to automatic updates. I have been unsuccessful in finding any way to turn off automatic updates on this plugin either in the dashboard of my WP website or in the Settings section of my Envato account. How do I turn off automatic updates?
If you’re using Envato extension/plug-in, you can just disable it
At first you should contact with the author of that item. Otherwise, you can hire a freelancer from studio.envato.com to get your goal. Cheers.
