Thanks that probably wouldn’t have solved the problem either because the fonts were going to italic, not changing weights and it was just headings but all formats. With the slow response time and lack of progress toward a resolution, I installed a google fonts plugin on the site which was able to override whatever the theme was doing and resolved the issues on Safari.

So problem solved, but not resolved through finding what was causing it in the first place.

I have now implemented the following, cleared cache, and still do not have a resolution to the issue.

/* Fix for https://kriesi.at/support/topic/font-manager-handles-font-files-with-suffix-regularitalic-wrong/ */
if ( ! function_exists( ‘enfold_add_missing_google_font_filenames’) ) {
function enfold_add_missing_google_font_filenames($enfold_font_manager_types) {
return array_merge($enfold_font_manager_types, array(‘regularitalic’ => array( 400, ‘italic’ )));
}

add_filter( ‘avf_google_fonts_style_definitions’, ‘enfold_add_missing_google_font_filenames’, 10, 1 );
}

It has not. We have updated the theme as recommended. We have cleared cache (which was done originally before you suggested anyways) multiple times. And the problem persists.
