[Plugin: Custom Login] DISALLOW_FILE_EDIT breaks plugin

I am using the following setting in wp_config.php:
define( ‘DISALLOW_FILE_EDIT’, true );

Started using this when focusing on security and this setting is adviced to make your site more secure. However, after using this setting the settings dissapears from the settings menu. When using the link from the plugin page, it says “You do not have sufficient permissions to access this page.”
