For those of you using sqlyog to do their upgrade via database structure and datasynchronisation the problem you encounter is that in later version of boonex the passwords are encrypted. So if you are upgrading from say version 4.1 to version 6.14 than your passwords will not work as this release has encrypted passwords.

Previously it has been suggested to
Code:
UPDATE `Profiles` SET password = MD5("password")
This will reset all passwords to password which is not ideal.

The below will allow you to run a php script and keep the passwords the user originally have but just encrypt them.
