Error warnings on home page

I’m running into an issue with a site I built using the Shapely theme but customizing using Visual Composer. The home page is displaying error notifications at the top of the browser. Can someone help me fix this or walk me through what steps I should take? I’m a UI designer- so code isn’t my forte.

Hi there

Hope you are having a good day and thank you for your question
The code is coming from visual composer plugin, this is not usual for our theme because i know a lot of our customers are using visual composer as a page builder so, i think its better and logical to get in touch with visual composer support staff
