Hi Fred,
Thank you for choosing our theme.
I check your site on Safari Version 12.0.3 (13606.4.5.3.1) on macOS High Sierra 10.13.6 it still work well.
Which version of Safari you’re checking. The latest version of Safari on Windows outdated so long from 2013 and Apply drop support.
If you use Window we recommend use other browser (Chrome, Firefox, Opera, Edge).
Kind regards
Harry
