[Plugin: Front-end Editor] This plugin breaks every elegenttheme.com theme

Unfortunately, I don’t have an account at https://elegantthemes.com so I can’t do any testing.

Try disabling the “Post title” editable field from the plugin’s settings page. That’s the one that causes the most problems, usually.

yup, that did the trick. It’s not broken now, but there are some other oddities – would you like a login to one of my client sites to take a look?

Please describe them first.
