If, in Chrome browser, you have the error 'Aw, Snap! Something went wrong while displaying this page.' you're probably using the new Animated Headings Effects wrongly and you haven't linked any Font Family to the headings you're animating.
If you use the Animated Headings Effects, make sure you have a valid Font Family connected to the headings. We invite you to check in your Theme Options → Customize → General → Heading Font Family if you have a valid value assigned.
Alternatively, you can check if the Page Builder → Heading → Font Family module has a valid value assigned.
