How to remove 'Posted on…'

Hi Ben,

You have these alternatives:

• WPP filters to customize the HTML output and have that text string removed. This is the recommended way to do it.
• Modify WPP’s directly, and remove that string from the code (not recommended, since changes will be lost after next update). Open wordpress-popular-posts.php using a text editor, find:
  $stats[] = '<span class="wpp-date">' . sprintf(__('posted on %s', $this->plugin_slug), $date) . '</span>';
  … and replace it with:
  $stats[] = '<span class="wpp-date">' . $date . '</span>';

Don’t worry. Try this:

/*
 * Builds custom HTML
 *
 * With this function, I can alter WPP's HTML output from my theme's functions.php.
 * This way, the modification is permanent even if the plugin gets updated.
 *
 * @param   array   $mostpopular
 * @param   array   $instance
 * @return  string
