Deletes post content in edit page

Plus One @paul Phillips – confirmed in WP 4.5, opening hours also breaks the Divi 2.7.5 page builder. (although Page builder also integrates the inbuilt TinyMCE as well).

SOLVED.

Update the library URL Jquery in \classes\OpeningHours\OpeningHours.php to solve the problem with the editor in version 4.5.2

Change URL jQuery in line 114.
