whitelist pages expects parameter 1 to be a string, array given line 607

Warning: unserialize() expects parameter 1 to be string, array given in /home/gothamvo/public_html/wp-content/plugins/wordpress-firewall-2/wordpress-firewall-2.php on line 607

Above error was encountered when trying to whitelist the following:
http://www.gothamvolleyball.org/wp-admin/admin.php?page=tablepress&message=success_import_wp_table_reloaded

I entered in

Pages            Form Variables
*                    page=tablepress

and received the above error I then tried the following:

admin.php      page=tablepress
admin.php        ?page=tablepress
*                      ?page=tablepress

and nothing worked but it did seem to erase the Form Variable that I had previously whitelisted :/
