Hello,
Both the URL which you shared display a wishlist heart icon. But as you said the icons are broken in your site. To fix this try to regenerate the CSS from WoodMart >> CSS generator.
Also you need to make sure that the “http” or “https” used in URL must be the same in both “WordPress Address (URL)” and “Site Address (URL)” from Settings >> General.
After doing this if the issue is still there then share you site login credentials so I can test and help you out.
Best Regards.
