Hi, I have a website running on Pagely hosting, so they will update your WP core continuously, and you can’t do anything about it.
So I have discovered an issue with the ACF Plugin and I can’t roll back it was all good till WP 4.2.2
The issue is classic the TinyMCE editor is broken.
In console I get this:
Uncaught TypeError: this.$right.find(…).sortable is not a function
I had this similar problem in previous versions of WP and ACF and I have my own way to fix it, but it will be probably good to report it and you should push an update to the plugin so all of the others affected will get a fix for this issue
The editor works, you can write in it, but everything is outputted in <p> tag, none of the other html tags works, for example hyperlink title etc. also there is an issue with some shortcodes
I think you should investigate this ASAP and push an update to fix this 🙂
