It's all gone away…

Plugin no longer displays any results. Tried it with the widget and the following code in the template:

<?php WPPP_show_popular_posts( "title=&number=5&days=100&category=22&show=posts&format=<a href='%post_permalink%' title='%post_title_attribute%'>%post_title%</a>" ); ?>

but it returned no results.

Jetpack is returning plenty of current stats, but the plugin gets nothing. I tried to download the debug file on the FAQ, but it returned a 404 error.

Many thanks for any guidance you can provide.
