DPS with CMS Integration

Hello:

I'm implementing DPS with the Wordpress CMS and the FolioAuthor plugin and when I try to preview and articles on the iPad and in the browser, I only see the following error:

Error: Constant WP_MEMORY_LIMIT already defined in /var/www/wordpress/wp-config.php on line 92

I am attaching a screenshot from my computer so I hope someone can help me out with this.

Thanks in advance.
