There are two main reasons why you may not be able to upgrade:
- The privileges are set to "owner" and Contact the project owner and ask him to change the privileges, or Please ask the owner to upgrade to a new card.
- Your credit card is disabled → The registered credit card is no longer in use. Please try a different card. We are unable to pay with debit cards.
If the above does not resolve the problem, please contact us and we will be happy to assist you.
