installation problem

[krattila]

I already installed the Mantis 1.2.5. with MySQL. the databasse name is Matis (I pre-created.)
On the buttom of login page I receive this warning:

SYSTEM WARNING: Unknown: 1 result set(s) not freed. Use mysql_free_result to free result sets which were requested using mysql_query()

When I try to login, it's accept the password but I receive a blank webpage.

Any idea?
