what wordpress permissions should i add to allow plugin and theme installation

Are you getting the following error message in wordpress when trying to upload a new theme or plugin?

This can be solved sometimes if your file permissions are already correct by adding the following:

In your server go into the main wordpress directory and edit the wp-config.php file.

nano wp-config.php

Add the following code to wp-config.php:

define('FS_METHOD', 'direct');
