I hope you are well today and thank you for your question.
Could you please clear the cache used on your shared site and temporary disable it so that I can troubleshoot it?
Also you can display Google map on your site by using Map content element as shown in the attached screenshot.
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson & toolset plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
If it is a conflict issue between Unyson plugin that provides mega menu functionality and toolset plugin that displays Google map then you can contact the plugin authors to resolve it.
You can also disable the Mega menu on your site and instead try using following free Mega menu plugin.
