[Plugin: PHPBB Single Sign On] Error_log Wierd entry

In extension to having the issue described here : http://ww.wp.xz.cn/support/topic/plugin-phpbb-single-sign-on-auth-mode?replies=1

I also seems to have below errors in my error_log file for WP,

I can see that plugin seems to look in wrong database for grabbing data.

Anyone know where i can change the database the plugins look into.

the xxxxxx represent username from webhost.

my phpbb3 database is named : xxxxxx_phpbb
