I just transferred my site from a shared hosting to a VPS hosting account (both on Arvixe), and suddenly ALL my users' passwords are wrong. The only account that works is the main Admin account. The users CAN receive password reset emails, but the password in those is also wrong.
I have gone through all the steps of clearing the cache, turning off the spam blocker tools, changing passwords manually, replacing the member.php file, etc. It worked perfectly fine on the old account and still does! Does anyone have any ideas?
