Hello to all!
I am getting next error in Drupal 7 instalation:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘webform_client_form_86’ not found or invalid function name in drupal_retrieve_form() (line 841 of /var/www/vhosts/example.com/httpdocs/includes/form.inc).
What does it mean? What is the way to solve it?
Thank you very much
