 * Now that I have updated to 3.0.1, all my documents show as Page Not Found. I 
   tried to upload a new version and received the following error “Fatal error: 
   Class ‘Document_Revisions’ not found in /home/doc/html/wordpress/wp-content/plugins/
   wpdr-simple-downloads/includes/wpdrsd-taxonomies.php on line 109”

 * Hi !
 * Add same kind of problem with Wp-document-Revisions-Code-Cookbook after updating
   to 3.0.1
 * Try replacing :
 * `$wpdr = Document_Revisions::$instance;`
 * by :
 * `global $wpdb;`
 * Let me know 😉

 * Please note this error is caused by the WP Document Revisions Simple Downloads
   plugin not being updated to work with the 3.0.0 and above versions of WP Document
   Revisions.
 * for the fix see:

 * Also if after the fix you are getting 404 errors when trying to view or download
   files you have to go to Settings > Permalinks in the WordPress Admin Menu and
   click the “Save Changes” button. That will rebuild your permalinks and fix the
   404 errors.

 * Previous Link I posted to a fix only half worked so don’t use that link or fix.
 * For updated fix please see:
