The transaction status appears as "blocked". Why?

Find below a list of the possible status messages:

• started — a payment has not been made, or payment notifications have not been set up;
• paid — a payment has been made;
• blocked — a payment form is filled, but the payment is yet to be made. A status message was not sent to CRM because an appropriate box was ticked in your Payment system (Site settings → Payment systems, open your Payment system and check if the box below is ticked):

• sent — the form was filled but not paid. The status messages were sent to CRM because the box was left unticked in your payment system settings
