password recovery in localhost

[creon]

I can confirm that after I updated 4.1 to 5.0 I had the same problem.
After restoring old crypt.helper.php from a backup, my password worked again.

p.s sorry for the necro post

Do the trick below to get rid of the outdated crypt helper.

1. Login in Elxis administration
2. Delete the old crypt.helper.php file and upload the new one from Elxis 5.x. Click on any administration page once per 5-10 minutes in order not to get logged out.
3. Go to users > edit your account and change your password (you can set the same password if you like). You are ready!

If you have more users you can change their passwords or they can change them with the "I forgot my password" feature in users central.
