Blockchain.info wallet address has changed over night..

[pollen_bit]

Is that normal?

[Abdussamad]

Nope. Are you sure it has changed?

[marcovaldo]

It can't change. What is your address?

[tom1]

Hard to believe ... perhaps you have more than one account?

[Welsh]

It shouldn't change. Are you totally sure you are in the same account as before? Did you have any Bitcoin in it? If so, was that Bitcoin transferred to you're new address? I would suggest contacting the owner through this forum or the website itself. They would most likely respond with a answer or they would look into it for you. However, the address shouldn't change and you should double check you haven't registered more than one account and you are using the Identifier for the particular account you are trying to access.

This can happen if you used the android app and generated an address with it. There was a bug with Android's random number generation, you could have generated weak addresses - so piuk pushed out an update and weak addresses are automatically regenerated with the funds swept.
