In your wp-config.php you will find a line that reads (most likely) like this:
REPLACE this with (or if it does not exist simply add the below)
define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false);/*this should NEVER be true for production sites*/
Note: this MUST be before
/* That's all, stop editing! Happy blogging. */
Which will generate a file “wp-content/debug.log” if and when any errors are encountered.
Check this file for errors if you need to find out where things might go wrong

If you have issues with WPPizza – or WordPress in general for that matter – I would highly recommend the following resource(s) to narrow down where your issue(s) might be
As I could not say this any better, forgive me for simply providing the links above. I would, however, especially recommend the “Troubleshooting Plugins” section on the perishablepress.com link ; about 2 thirds down on that page.
Of course, if you have followed the recommendations on those pages without being able to solve your problem and still have issues with WPPizza, please get in touch via the usual channels (forum, contact form, emails)
