I followed this tutorial,http://wp.tutsplus.com/tutorials/plugins/a-guide-to-wordpress-custom-post-types-creation-display-and-meta-boxes/, I thought very closely but when I finished it, my plugin works but it gives every other page on the site the WSOD! Once I deactivate the plugin, my other pages work again. I am running this on my mac using MAMP if that helps at all. I wanted to get it all finished before I upload and test online even though my site isn't live.
Below is my code. Any ideas on what the heck I did wrong? Thank you so much for any help you can give me.

I took out some parts but narrowed it down to this section below that was causing the problem.
// Custom Template Dedicated to Custom Post Types
add_filter( 'template_include','include_template_function', 1 );
function include_template_function( $template_path ) {
if ( get_post_type() == 'nm_portfolio' ) {
if ( is_single() ) {
// checks if the file exists in the theme first,
// otherwise serve the file from the plugin
if ( $theme_file = locate_template( array ( 'single-nm_portfolio.php' ) ) ) {
$template_path = $theme_file;
} else {
$template_path = plugin_dir_path( __FILE__ ) . '/single-nm_portfolio.php';
}
}
elseif ( is_archive() ) {
if ( $theme_file = locate_template( array ( 'archive-nm_portfolio.php' ) ) ) {
$template_path = $theme_file;
} else { $template_path = plugin_dir_path( __FILE__ ) . '/archive-nm_portfolio.php';
}
}
return $template_path;
}
I deleted add_filter( 'template_include','include_template_function', 1 ); and it seems to work fine now.
Below is my code all together that works and has been edited to get rid of a few things that I didn't really want anyway.
