[Plugin: Yet Another Related Posts Plugin] Php error on configuration page

Hi,
I installed your plugin, I still don’t know if it works as expected cause my blog is new and still under construction.
However, in configuration page, I see this error:

PHP Error Message

Warning: Invalid argument supplied for foreach() in /home/a5016048/public_html/wp-content/plugins/yet-another-related-posts-plugin/options.php on line 416

Looks like he doesn’t like the<?php foreach (glob(STYLESHEETPATH . '/yarpp-template-*.php') as $template): ?> line; in addition, echoing STYLESHEETPATH it returns the path of my WP main theme (mystique)!

The result, is that I cannot choose a template…
There’s another way to choose one instead of using this checkbox? In the surrounding line of line I see only php echos and a js function…

Both version 3.1.3 and 3.1.4b2 give this error.

Thanks for your time, bye!
