Hello, Featured Slider doesn’t work anymore. It happens after update wordpress or the plugin. I tryed to turn on/off but with no result. Any suggestions? Here is a link to my website.

Try to disable all plugins to see if that does anything.
However, from what I see inside your website source is that your footer is completely broken and none of JavaScript is loaded properly inside your website footer, so not just slider but nothing JavaScript based is now working on your website.
If disabling plugins doesn’t help try to delete this theme completely and install it again. No customizations done via Theme Options or WordPress Customizer will be lost. It will just replace all broken files.
Let me know if this helps.
