I received this from Godaddy after the website crashed and had to Godaddy WordPress support to get it fixed.
That notice is caused by Essential Grid plugin. It is only a notice, not warning or similar, so you can either ignore it (it disappears after debugging is turned off), or we can update it to the latest version (your current version is outdated). If you want us to update it you will have to send us the latest version (if you purchased it through the CodeCanyon, you can still download the latest version on Envato website.
Are there any issues with the essential grid plug-in
You can contact the developer of the Essential Grid plugin to find out. I will say their advice to update to the current version is solid and should be followed regardless.
