 * When using the plugin to insert issuu to post, it does not sync to Issuu, and
   drop down does not work.

 * I’ve the same problem that has been noticed only this morning.
    My quick and 
   dirt workaround was to edit the file:
 * wp-content/plugins/issuu-pdf-sync/inc/class.admin.php
 * and comment the following lines (about 375):
 *     ```
       if ( !isset( $form_fields ) || empty( $form_fields ) || !isset( $attachment ) || empty( $attachment ) )
                return $form_fields;
       ```
   
 * As far as I could understand, WP 3.5 modified the attachment_fields_to_edit hook
   behavior and the $form_fields variable does not get passed anymore.
    Commenting
   out those two lines made it work for me, but I don’t know if it’s going to break
   something else.

 * The developer [@benjaminniess](https://wordpress.org/support/users/benjaminniess/)
   has given us access to the plugin. We will try to update the plugin next week
   and solve the known issues.
