I checked your website and saw you have added a Typekit font script reference inside the customizer which is wrong. Please kindly remove that code as you can not use the tag inside Pro > Launch > Options > JS/CSS
If you want to add such a reference kindly install the Child Theme and follow this link:
https://theme.co/apex/forum/t/customizations-actions-and-filters-in-x/208 (wp_head is the hook which you should use)
Also kindly check the header builder. Are you having a separate header for the homepage and another for the rest? If that is the case there must be something problematic there. Try to assign no header and see if the footer works ok.
And at last, kindly make sure that you clear any possible cache plugin you may have.
