XF 1.2 Password incorrect after changing host

Is it all users or some?
Presumably your account wasn't affected as you were able to log in to the ACP?

If you downgraded from PHP 5.3 to PHP 5.2, this can happen -- with PHP 5.3, a more secure password scheme is used.

Note that PHP 5.2 is completely unsupported by PHP now, so it's strongly recommended that you don't use it.
PHP version 5.3.27

The old server was 5.2

All users of the forum are affected including me. I had to reset my password via sql query.

All my add-ons are disable and I tried to use diferents mysql backups, but no luck at all.

Do you have any suggestion?

Thanks for your help

Can you submit a ticket with FTP details? I would need to know a password that doesn't work though. There isn't any known issue that would cause this (other than the 5.3+ -> 5.2 issue, which you say isn't happening).

There isn't a way to bulk reset and email users passwords.
