Thanks for your helpful advise. My website is called zenergi.com.au and under the the classes menu is the new review menu which is the page I decided to put the Gwolle plugin. It is now working after I have installed the plugin you suggested (albeit temporary).
I noticed in my dashboard it says the culprit is:-
https://zenergi.com.au/wp-content/plugins/xtender/assets/front/js/scripts-min.js: Attribute selector with \’#\’ must be quoted: .xtd-modal–inline > .vc_btn3[href^=#], a.xtd-modal–inline[href^=#]
I do have a plugin called extender. I think that is the culprit. It doesn’t explain the expired keymap error as I have no google maps on my website. I am still stumped about that one. Maybe it is in a plugin of some sort???
