Wordpress: WP_Query search criteria on 'post_name'

Instead of

'post_name' => 'rebecca-atkinson',

use:

'name' => 'rebecca-atkinson',

php wordpress content-management-system

In addition to my answer in the comments above, I thought I'd post it as an official answer too:

I have to use 'name' and NOT 'post_name'.

For example:

'name' => 'rebecca-atkinson'

Hope this helps someone in future.
