SQL error APPLICATION ERROR #401 Database query failed. Err

[sjenkinsdc]

I've searched in these forums and online and can't yet find a solution to this issue. I am using Mantis v1.1.7, mySQL v4.1.7 and PHP v4.3.11.

This is the error I receive after having installed mantis:

APPLICATION ERROR #401

Database query failed. Error received from database was #1267: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' for the query: SELECT id
FROM mantis_user_table
WHERE username='administrator'.
