    Please check your file permission from your hosting panel. The permission must be 0755 for file/folder. If you are using a vps(virtual private server) then you must ensure that the owner of your installation is PHP aka www-data. Another reason could be wrong root folder path/url. Inserting a correct root folder path/URL should fix the issue

    I checked all items above and did not work!

    Also I wrote

    define( 'DISALLOW_FILE_EDIT', false );
    /* That's all, stop editing! Happy publishing. */

    in wp-config.php
