REZOLVED !!!

I executed the following SQL query on your database using phpMyAdmin to reset my currencies

TRUNCATE TABLE `ps_currency`;
TRUNCATE TABLE `ps_module_currency`;
INSERT INTO `ps_currency` (name, iso_code, sign, blank, conversion_rate, format, deleted) VALUES
('Euro', 'EUR', '€', 1, 1, 2, 0), ('Dollar', 'USD', '$', 0, 1.47, 1, 0), ('Pound', 'GBP', '£', 0, 0.8, 1, 0);
INSERT INTO `ps_module_currency` (`id_module`, `id_currency`) VALUES (3, 1),(3, 2),(3, 3),(4, -2),(6, 1),(6, 2),(6, 3);
