I moved a small SilverStripe site today and the passwords stopped working, and I just can't work out what's happened. I've looked in both databases(via PhpMyAdmin) and the table structure of the Member table is identical and the data is identical, yet the password won't work. I can reset the password to get it working, but I have another 2 sites to relocate over the next few weeks, one has lots of members that I don't want to have to get them all to regenerate their passwords. Does anybody know why this would happen???
