Hello,
First of all thanks for choosing our Theme, we are glad to be you in WoodMart WordPress family :-)
.
As the square boxes are shown except of icons in your site to fix this try to regenerate the CSS from WoodMart >> CSS generator.
Also, please go to Theme Settings and resave it and check your site after removing the browser cache.
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.
