 * I am having the following issue:
    call_user_func_array() expects parameter 1 
   to be a valid callback, function ‘arphabet_widgets_init’ not found or invalid
   function name in wp-includes/class-wp-hook.php on line 287
 * The contact form is not delivering the email. The WP-SMTP plugin is delivering
   the test mail.
 * The Debug shows following issues : Warning: call_user_func_array() expects parameter
   1 to be a valid callback, function ‘arphabet_widgets_init’ not found or invalid
   function name in /home/jencoder/public_html/wp/wp-includes/class-wp-hook.php 
   on line 287
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcall_user_func_array-expects-parameter-1-in-wp-includes-class-wp-hook-php-287%2F%3Foutput_format%3Dmd&locale=en_US)

 * Whatever plugin or theme has the call for `arphabet_widgets_init` has it coded
   wrong. You need to ask in that support forum.
    Same thing for the contact form,
   which is not a part of WordPress.
