Hello,
As you said that icons not showing in your site. But when I test your current domain almost all the icons shown just fine: https://jmp.sh/oDwnIE8
In case if you used some other custom icons and they are not shown then you can do the following steps to fix this:
1. First check the URL from general settings that the url should be http or https but the same as the website.

2. Resave the Theme settings from the Theme Settings option.
3. Must regenerate the CSS from CSS generator from the WoodMart >> CSS Generator.
Best Regards.
