Same for me. Visual editor is broken. Its a plugin but an essential plugin for the theme I’m using – Goodlayers Flawless – which uses the Goodlayers Shortcode plugin. It adds an icon to the visual editor. Once I delete it its ok but I need it.
Equally as bad is the fact the WooCommerce Shortcode button is now gone from my sites visual editors. I develop for around 6 WooCommerce shops – this wont do..
🙁 What do we do?
