I gotta admit I haven't tested this plugin on 1.5.8 yet, primarily because I have v2 planned for later this month...
Assuming your logs aren't modified, you're using a template named "CUSTOM" - did you add the files from YOUR_TEMPLATE do that directory? If so, this was probably a mistake because the 1.5.8 version of that file is slightly different and tpl_index_default.php should look something like this:
Code:
<?php
/**
* Page Template
*
* Main index page
* Displays greetings, welcome text (define-page content), and various centerboxes depending on switch settings in Admin
* Centerboxes are called as necessary
