 * Hello there,
 * My site is showing the following error:
 * _Warning: call\_user\_func\_array() expects parameter 1 to be a valid callback,
   class ‘CAF\_front\_filter’ does not have a method ‘tc\_caf\_filter\_all\_text’
   in /wp-includes/class-wp-hook.php on line 309_
 * In the code, line 309 is:
 * $value = call_user_func_array( $the_[‘function’], array_slice( $args, 0, (int)
   $the_[‘accepted_args’] ) );
 * Do you know how to solve this?
 * Thank you very much for this amazing plugin!
