Frequently asked questions (FAQ)

In the payment process I see blank page. Why and how to fix it?
Answer: Module using a function available in PHP 5.4+ in order to generate payment security sign. Your store running on PHP server 5.3 or less. Please update your PHP server on 5.4+ or ask your webhosting provider with this request.

Why after module testing on Tatra banka website still "Timeout" message appear?
