Since the latest upgrade of wordpress to version 4.2.2, I’m seeing an error in my console :
Uncaught TypeError: f.className.indexOf is not a function
g.observe.childList @ wp-emoji-release.min.js?ver=4.2.2:4
It seems it is an issue for all wordpress users, who upgraded to 4.2.2. I saw a solution with a plugin to disable emojis, but I don’t want to install an additionnal plugin. Anyone knows a turnaround or solution for this ?
