image can’t be found. So i put the code direct into style.css. It worked well. (had to modify stlye.css again after latest theme update, no biggy)
it doesn’t work with Safari and now, it doesn’t work at all.
thank you very much for your timely response again!
I have to apologize, because the mistake was on my side. Due to your hint I figured out, that I didn’t save the icon in the /images folder, but in the /theme/generatepress/images folder. Due to the latest update of your theme, the file was deleted/overridden by that.
Now I have stored that image in the appropriate folder and it works fine! The phenomena of showing the icon or not was because of browser cache respectively of the cachify plugin, i am using.
