[Plugin: Shortcode Reference] Big Ol' Error

WP: 3.1.2
Domain: http://www.newurbangirl.me
Theme: TwentyTen + Custom Child Theme w/CSS Changes
Plugins: Several, including Shortcode Exec PHP, Simple Facebook Connect, Simple Twitter Connect, Delicious Tagroll Shortcode, Subscribe2, Stout Google Calendar and others.

Here is the issue: I use several plugins that offer shortcodes as part of their features. In addition to this, I have shortcodes defined in a Custom “Child Theme” functions.php for TwentyTen AND I have some defined in Shortcode Exec PHP. Shortcode Reference appears to display most of these, but when trying to insert a shortcode, this results:

Warning: fopen(/home/newurban/public_html/wp-content/plugins/simple-facebook-connect/simple-facebook-connect.php) [function.fopen]: failed to open stream: No such file or directory in /home/newurban/public_html/wp-includes/functions.php on line 4284

Warning: fread(): supplied argument is not a valid stream resource in /home/newurban/public_html/wp-includes/functions.php on line 4287

Warning: fclose(): supplied argument is not a valid stream resource in /home/newurban/public_html/wp-includes/functions.php on line 4290
Plugin: simple-facebook-connect
No documentation found.

This appears to occur regardless of the source of the shortcode. However, if the shortcode is defined in the parent theme functions.php, it appears to work.
