Can't change my password

[IveBeenVeryStupid]

It goes through the motions and says successfully updated details but if I log out I can only log back in with old password.

Hi there IveBeenVeryStupid,

How odd! Could you let us know what device and browser you're using? Could you also try clearing your cache and cookies?

Chrome on Samsung galaxy. I'll clear them now, thanks Katherine.

Cleared everything and tried again, still not changing!

Hi again, that does seem a bit strange. Can you log on using a different device, just as a control experiment...Let us know how you get on.
