Just installed Openfire and can't log into spark. Error message of wrong username and password.

Openfire just installed on server. Downloaded Spark but when logging in it keeps saying username and password are wrong. I've read a lot of posts to try to find a solution but have had no success.

Here is the Spark error log:
