password change ???

About a week ago I was told to change my password because it was a year old, thought that was a bit odd since I have been here for a while and never had to change it in past years, anyway I changed it and everything is ok when I access the site with my laptop however I cant seem to get in with my tablet, keeps saying I entered an invalid password and I am now locked out because I tried 5 times , any advice ?

Did you try clearing out cookies and refresh?
