What is the verbatim error message?
You don't add €10.99 (cash credit) to your My48 account, you need to buy a monthly membership plan.
When were you last able to successfully buy a membership plan?
Is your payment card still valid, not frozen via your online banking, and there are sufficient funds in the account if it's a debit card?
If you need to contact 48 support about this then see the links in my signature below.
