CDATA error for RSS feed

Assuming that the correct URL is http://talentsofautism.com

The problem is with a call to colorful_continue_reading_link, which is not a WordPress function.

Fatal error: Call to undefined function
colorful_continue_reading_link() in
/home/content/42/9357842/html/talentsofautism/wp-content/themes/d5-colorful/functions.php
on line 67

A search suggests that it is part of the D5 Colorful theme, and that is the theme you are using.

Theme Name: D5 COLORFUL
Theme URI: http://d5creation.com/2012/08/06/colorful/

Author: D5 Creation
Author URI: http://d5creation.com/

It appears that something is wrong with your theme. That function is used twice in the theme’s functions.php but I don’t know where it is defined. It is a relatively simple theme, I don’t know where else to look for the function. I am leaning toward calling it a bug.

If you comment out the two functions that use colorful_continue_reading_link it should correct this issue:

//  Replaces "[...]" (appended to automatically generated excerpts) with an ellipsis and colorful_continue_reading_link().
//  function tied to the excerpt_more filter hook.
//  function colorful_auto_excerpt_more( $more ) {
//      return ' …' . colorful_continue_reading_link();
//  }
//  add_filter( 'excerpt_more', 'colorful_auto_excerpt_more' );
//  
//  Adds a pretty "Continue Reading" link to custom post excerpts.
//  function colorful_custom_excerpt_more( $output ) {
//      if ( has_excerpt() && ! is_attachment() ) {
//          $output .= colorful_continue_reading_link();
//      }
//      return $output;
//  }
//  add_filter( 'get_the_excerpt', 'colorful_custom_excerpt_more' );

That is a bandaid. Contact the theme developer to find out what colorful_continue_reading_link should be.
