 * Here is the error msg I get:
    Fatal error: Cannot redeclare custom_excerpt_length()(
   previously declared in /home/irispele/public_html/wp-content/themes/irispeleg/
   functions.php:5) in /home/irispele/public_html/wp-content/plugins/blog-designer/
   blog-designer.php on line 179
 * Isn’t the whole idea of the plugin to run independent of the default blog design?
 * Thanks,
    Zohar

 * here is solution….
    function name ‘custom_excerpt_length’ in our plugin is conflicting
   with your theme’s function.
 * In our plugin’s “blog-designer.php” file, do the following changes.
    1) rename
   the function name ‘custom_excerpt_length’ with ‘custom_excerpt_length_blog’.
 * 2) replace line
    add_filter(‘excerpt_length’, ‘custom_excerpt_length’, 999) with
   add_filter(‘excerpt_length’, ‘custom_excerpt_length_blog’, 999)
 * Thanks
