In-page navigation not working

[GenjiCreative]

I have several anchor links in my navigation that should bring you to a specific ID when clicked. However, when I click, I receive the following error in Chrome’s consol log:

Blockquotejquery.js?ver=1.12.4:4 Uncaught TypeError: n.easing[this.easing] is not a function
at init.run (jquery.js?ver=1.12.4:4)

at a.fn.init.each (jquery.js?ver=1.12.4:2)
at a.fn.init.queue (jquery.js?ver=1.12.4:3)

I have tried deactivating all plugins except cornerstone, but I still receive this error. I see that the site is pulling jquery version 1.12.4:3 and jquery migrate is also installed. Could this be the issue? If so how do I troubleshoot this?

Hi @GenjiCreative

I’ve checked your website and I can see your server is running PHP 5.4.13, this is a very old version of PHP released back in 2013, please update to at least PHP 5.6 and recheck this issue, you can get in contact with your hosting provider in case you don’t see an option in your cPanel to update PHP. WordPress itself recommends PHP 7.2 or greater!

Thanks.
