I have a node that I can see on my site, but when I try to edit it I get the error:
Notice: Undefined index: my_node_name_node_form in drupal_retrieve_form() (line 763 of /home/sites/my-site-url/includes/form.inc).
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'my_node_name_node_form' not found or invalid function name in drupal_retrieve_form() (line 798 of /home/sites/my-site-url/includes/form.inc).
I cannot see the node by going to 'content'.
I believe that what has happened is: I deleted a Content Type that was redundant on my site without realizing that there was a node of that type on the site. I guess that now the node doesn't its content type this is stopping it from being deleted.
I would like to know how to delete this node, or failing that unpublish it.
I know the NID of the node to be deleted.
I guess that one way of doing this would be manually using phpmyadmin. For this approach I would need some guidance on how to go about this as I am not very familiar with either how nodes are spread across the tables in the database or working in phpmyadmin.
