I installed your theme froday. Everything is fine except some icons are missing on the category menu on the left side of slider. I tried to install 3 times but facing the same problem http://prntscr.com/jxh0xi
First of all, thank you for purchasing Froday WordPress Theme.
You can set the category icon from Dashboard > Products > Categories > Edit a category. (Please see the attached file)
You can check the following url to see the available icons.
