 * Hi,
 * When I install and activate your plugin I get the following error:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, no
   array or string given in /home/tiffdemohostserv/public_html/HairandSpa/wp-includes/
   class-wp-hook.php on line 298
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/tiffdemohostserv/public_html/HairandSpa/wp-includes/class-wp-hook.php:
   298) in /home/tiffdemohostserv/public_html/HairandSpa/wp-includes/pluggable.php
   on line 1179
 * Do you know how to fix this?
 * Thanks for your time.
