When you go to edit a page in WordPress, you see an empty page.  In actuality, the text is there, if you highlight it, you will see it, but there is no visual editor.

  1. Go to edit a page in Chrome
  2. Turn on Developer Tools
  3. You’ll see it says: ReferenceError: TinyMCE is not defined

PROBLEM: This is probably due to a conflict with your theme or a plugin.


Open your wp-config.php file and add the following line, right before “Stop editing”.. see below

define(‘WP_DEBUG’, false);
define(‘CONCATENATE_SCRIPTS’, false);
/* That’s all, stop editing! Happy blogging. */

Save the file, and put it back onto your site.  The problem should be resolved!

By defining the constant as false you are practically forcing WordPress to load each script on the administration page individually rather than collectively. So in that case – If one script fails to load and work correctly, the others can still continue to operate correctly.

This is a recommended setting for debugging and local development. However, in this case, it is probably a symptom of a problem, and not the problem itself. You should isolate the problem and fix it., but this will fix the problem until you do that.
