Enable debug output
The debug output is a great way to see what values that exist for each post.
![debug-too-settings](../../../wordpress/wp-content/uploads/2012/10/debug-too-settings.png)
To enable: Go to Settings -> Simple Fields -> Select debug in the dropdown -> Save -> Visit site -> enjoy!
![debug-show-fields-link](../../../wordpress/wp-content/uploads/2012/10/debug-show-fields-link.png)
This short text + a link to expand will be outputed. Click the link to…
![debug-tool-output-expanded](../../../wordpress/wp-content/uploads/2012/10/debug-tool-output-expanded.png)
… and the debug box opens up with information about all the added fields and their contents.
that’s nice.
