Hi, I got this message:
Warning: Missing argument 1 for WP_Subplugins_List_Table::bulk_actions(), called in /home/nichenin/public_html/wp-admin/includes/class-wp-list-table.php on line 768 and defined in /home/nichenin/public_html/wp-content/plugins/statpress-community-formerly-statcomm/classes/wpsubpluginslisttable.php on line 164
