Trouble after migrating to a new server


Hi, guys...
I've moved my mailwizz app to a new server following all the steps in this article:

Now, everything looks good from inside except that is not delivering... cron ok and files permissions, even the test campaign email is working, so the delivery servers are ok... when looking into de system logs I've got this error:

2018/06/05 19:44:38 [error] [exception.CDbException] [] SQLSTATE[HY000] [1044] Access denied for user 'goodbyi5_meil'@'localhost' to database 'tintach1_mw1'

what can I do?

thanks a lot!
