WordPress theme editor is missing

I'm attempting to get to the subject proofreader in WordPress.

The issue is that I can't track down the choice under Administrator Appearances - Proofreader and when I attempt to get to the page utilizing the connection http://www.nameofsite.com/wp-administrator/subject editor.php I get the mistake:

You don't have adequate consents to get to this page.

I'm signed in as a manager. For what reason mightn't I at any point track down the manager choice?

Solutions

It is most likely as a result of iThemes Security and its settings. Indeed go to wp-config and change DISALLOW_FILE_EDIT to bogus.

define( 'DISALLOW_FILE_EDIT', false );

Or then again switch it off here: Dashboard - > Security - > WordPress Changes - > Arrange Settings

Uncheck: Impair Document Supervisor
