Continuing "Update existing login" requests

When I login to certain sites, a small window opens and asks whether I want to update my login. Even I click Update, the message repeats every time I open the site and try to login. If it matters, cookies associated with these sites are persistent and don’t get deleted. Is thee a fix for this? Thanks.
