Good day When you go to other pages of the site through the navigation menu in the console, it displays the error specified in the screenshot attached below
I hope you are well today and thank you for your question.
Please update the theme on your site to the below latest version as described here https://support.shufflehound.com/updating-theme/
Please login to access this file
This can be due to plugin conflict on your site so please try temporary deactivating all plugins except Unyson plugin and WpBakery page builder plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.
I logged into your website and saw the javascript error also occurs for the default Twenty Twenty theme so it doesn’t seem the theme issue but your website issue so please contact your web host to resolve it.
