Hey @NikolasRigo,
Thank you for posting in the PayPal Community Forum, welcome back!
I am sorry to see you are having issues sending a payment, I appreciate how concerning this must be. First of all, I would ask that you ensure your email address is confirmed. Please also ensure you have a funding source (bank/card) added to your account and confirmed: How do I add a bank account to my PayPal account? & How do I add a credit card to my PayPal account?
I understand you have checked to ensure you have no cases or limitations. If there are limitations stopping you from sending money, you would find these on your Resolution Center after selecting 'Go To Account Limitations'.
Finally, I would ask that you check the following link: How do I confirm my identity? (CIP) (paypal.com) to ensure we aren't requesting that you confirm your identity first.
I hope this helps. Have a lovely day!
Rebecca.
