[Plugin: Yet Another Related Posts Plugin] Plugin not working. PHP errors.

Hi,

The plugin activates fine, and I can open up the options and make changes, but I’m getting PHP errors and the plugin just doesn’t work.

WP: 2.6.1
MyQSL: 5.0.41
PHP: 5.2.5

Upon activation, here are the PHP errors:
[26-Aug-2008 10:11:13] PHP Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /Users/preynolds/Documents/_SVN/sandbox/pl/wp/wp-content/plugins/yet-another-related-posts-plugin/includes.php on line 41

Upon refreshing a post, I’m getting an SQL syntax error:
