what doesn’t work exactly ?
It showed icons on the editor, but showed nothing on font end.
Thank you for your reply. Now I can fix the problem. So just FYI, I will provide what I found for you to make your plugin better (It’s great now ^^ ).
are there any debug notices ?
No. Sorry
do you have any other plugins installed ?
Well I tried so many plugin, but I deleted the other before install your plugin.
have you tried deactivating, your other plugins?
Yes, I have tried.
Have you switched to, or are you using the default theme?
Yes. And it worked when I switched to the default theme.
Well, what I found that is your plugin is worked great on default environment such theme from WP, buying theme, and etc. Unfortunately, it doesn’t work when I used a child theme (at all), even your plugin can work on a main theme.
I fixed the problem by adding a CSS code to my child theme CSS. Sorry I didn’t copy that one, but this code will make your CSS use FontAwesome (It disable when you use a child theme).
I hope you will be able to make it able to use with any child theme, because a child theme of WP is a great thing.
Cheers!
