problem saving contact

Hello,
I have a problem when I want to create a contact.
Everything goes right when I fill the boxes but when I press "Save", there's an error message which says "impossible to handle your request.
Does anyone have information to help me?

You have to know that it doesn't happen everytime. I've had this problem only 3 time during the past few days but everytime I have to wait an entire day before I can save the new contact. Also, It's never the same contact, so all the information are different.
