[SM-PLUGINS] problem with spamassassin+SQL plugin

[Andrew <an...@ar...>]

I've installed the Spamassassin+SQL plugin but it's not working for me. 
When I go to the Options page, I see the Spam Filter Configuration link 
but when I click on it, the right pane goes blank and stays that way. I 
don't get logged out of SM and I can return to the Options page or my inbox.

Spamassassin is working with MySQL. The database is running on a 
separate machine from SM and I'm able to manually connect to it from the 
SM box using this command.

mysql -u sa -h callisto.arda.homeunix.net -p <password>

I copied the sasql_conf.php.dist file to sasql_conf.php and modified the 
$SqlDSN and $SqlTable lines to suite my setup. Here they are:

$SqlDSN = 'mysql://sa:<password>@callisto.arda.homeunix.net/spamassassin';
$SqlTable = 'sa_userprefs';

I really don't know where the problem is since I'm not getting any error 
messages. If anyone can offer any advice, I'd appreciate it.

Versions of relevant software are:
sasql 2.3.2
SM 1.4.2
PHP 4.3.4
FreeBSD 4.8
