Hello,
1) I have updated plugin to latest version. We see the following when checking that page http://prntscr.com/j14rmw Please, follow the instructions and finish plugin configuration.
2) These warnings are related to Screets Live chat plugin and are not related to our theme http://prntscr.com/j14x1g . So we can do nothing because we are not plugin developers. We have posted question about them in comments area of the plugin https://codecanyon.net/item/wordpress-live-chat-plugin/3952877/comments?page=69&filter=all#comment_19196333 and we’ll inform you once get the answer.
Regards
