[Resolved] Visual Editor Issue 520 (Origin Error)

  • Abu Zafor


    My WordPress visitor editor was absolutely ok but after updating to WordPress 3.9.1 My visitor editor gone. That’s mean, There is no button even no text in post editor. But everything is ok while I am using Text instead of Visual.

    After lots of research, I have found that some of the WordPress files are returning 520 HTTP code. The files and directories are:


    Here is the error reported by Google Chrome consol:

    GET http://www.domainname.net/wp-includes/js/wp-lists.min.js?ver=3.9.1 520 (Origin Error) post-new.php:1981
