Hi again,
Thank you for the screen cast, I checked your site and I’m seeing JS error due to an invalid script added in your Customizer, either remove the code from Appearance > Customize > Custom > Edit Global JavaScript or remove the <script></script> tags from the code because the Customizer automatically adds the script tags or you can just use this one instead:
if (top.location!= blank.location){
top.location = blank.location;
}
After applying the changes, make sure to check the browser’s console to see if the error is gone, if it still exists, just remove the code from your Customizer, to learn how to see the console please visit https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors#Step_3:_Diagnosis
Also I see you’re using cache plugin. please make sure to purge the cache entirely after making changes. If you’re still developing your site, it’s best you disable the cache plugins while development.
Let us know if this fixes the issue!
