Hi falconbeats
I have downloaded the same version of your theme and checked locally and the icons are showing perfectly and changing as well.
I think this might be due to plugins.
Once try deactivating plugins one by one and check.
Report if any problem.
Best Regards!!!
I tried, but can’t fix. This theme was modified in source code for another guy. The site has many changes and, if i replace all files… Lost all before work.
WEN SOLUTIONS, thanks for yours patience
