Hi Erixz,
I had the same problem.
I solved it by inserting a piece of code after “$this->process_bulk_action();“
The code:
$query = “SELECT * FROM {$wpdb->posts}”;
$totalitems = $wpdb->query($query);
$this->items = $wpdb->get_results($query);
After that you should create a function “display_rows()”
Please refer to this website http://wp.smashingmagazine.com/2011/11/03/native-admin-tables-wordpress/
for the details about the “display_rows()” function. Make sure you read the comments because there are some mistakes in the code and users fixed them.
