Can't login to SquirrelMail after making password change for user in ISPconfig 3

[clttech]

I have had the server up and running for a while now. We had a user that needed to change their password, and we did now we can't log into squirrel mail. We can log in using a pop3 client. So I went to my account and changed passwords and now I can't log into squirrel mail. So I tried the old password it work fine, but the new changed password will not. Any ideas where I should look? Can't try that with the user because they forgot their old password.
