Warning: call_user_func_array()

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!
