I understand security and all that very well but does the site really need daily password expiration? i mean one day i login, i change my password and then the second day it isn't working so i have to retrieve it and then change it again cause that auto generated one will also expire. is that needed?
I don't know the answer but that is not normal. Try clearing cookies and login using the remember me option.
i have tried those two things, i used ccleaner even along with manually wiping the cookies and cache on firefox.
