OK, I believe I've fixed this. Here is what I did...

I changed (line 41) of the purgenow script:

$db->execute_query("TRUNCATE TABLE " . TABLE_PREFIX . "loginlog");

to this:

$db->query(' TRUNCATE TABLE ' . TABLE_PREFIX . 'loginlog');

Basically all you should need to do is change execute_query to query and add a space before and after TRUNCATE TABLE, after which the purges should start working correctly. In any case, this fix seems to work perfectly here. Now every time I execute a purge, the message "The login log has been purged" is properly displayed and all login entries are gone.
