Tabs not working after updating to PHP 7.3

Hi there, we’ve just updated the theme to the latest version and upgraded to PHP 7.3 and the tabs have stopped working:
I hard coded the tabs from an early version made in cornerstone, is there a way to make these compatible with the latest version?
Thanks so much, I’ve tried various things already at this point without any luck, any help is greatly appreciated.

Hi @jetlag,

Thank you for writing in, I see JS errors on your pages.

Since you just update your site, please clear all your caching features (plugin, server-side, CDN, and browser’s cache) so that the latest code from the update is in use. This will help you to avoid any potential errors.

Then do a Testing for Plugin Conflict, also if you have custom JavaScripts somewhere, please try removing those for a while and see if that resolves the issue.

If the issue persists, please do the common troubleshooting guide we provided here.
