How to fix the "lack of proper file permissions for uploads" problem?

Here is the error:

#Exception:0
Media files cannot be published due to lack of proper file permissions for uploads directory.

The solution is simple. Just add the following snippet to the wp-config.php configuration file of your WordPress setup:

​if (!defined('FS_METHOD')) define('FS_METHOD', 'direct');

That should fix the problem and if not, you need to talk to your hosting provider or network admin to fix the FTP problem.

Please note that this problem occurs whenever a plugin tries to access a file, but doesn't have write access, and tries instead to use FTP to access it. And please keep in mind that the Depicter uses the WordPress filesystem which tries to access files based on the way you have your install setup.
