Editor Feature is not Showing in WordPress

Editor Feature is not Showing in WordPress

Hi Friends, recently i am working on admin panel of my blog and all of sudden i have noticed that Editor Feature is not Showing in WordPress admin panel. To solve this issue i google and not found any link to solve this. I have tried with disabling all plugin’s , but still no success.

Finally i looked on my wp_config.php file and i have noticed that on top of it a line is added which seems to wired.

define(‘DISALLOW_FILE_EDIT’, true); 

I delete this line save my wp_config.php file and now i am able to see my Editor option under appearance tab.
