How to update the Revolution Slider
We include the plugin Revolution Slider in some of our themes.
If it states that there's an update available, you can't do it yourself! You need to wait the theme update, we always send the updates of the slider with the theme.
If you instead need/want to update the plugin yourself, then you can buy it here: http://codecanyon.net/item/slider-revolution-responsive-wordpress-plugin/2751380
You will need to install it on your website like any other plugin. If you have problems in removing our version of the plugin, please write a ticket in the support desk!
