Login to admin after site publishing

[rusjoan]

I published my site to remote host and now I can't login to admin with old credentials.

All config and DB same as on my local.

Tried to switch off "session fingerprint" and other stuff and it doesn't help me.

Any suggestions?

Thanks.

Try running this from a template file:

$u = $users->get('admin'); // or whatever your username is
$u->of(false);
$u->pass = 'your-new-password';
$u->save();

to reset your password.

I would also recommend to reset the password.

And here is an additional explanation:

Depending on the host's PHP version processwire uses the strongest available blowfish algorithm.

So all passwords become "invalid" if the password algorithm changes.

For example if your remote PHP version is above 5.3.7 and your local version is below that, processwire generates different password hashes.

There could be other conditions for differing password hashes, but basically it's that.

Thanks guys, so now I know a real reason of this issue. It's true that server and local PHPs has different versions

Changing user password under other admin account helped me
