I created a taxonomy with the same name as a content type. Now the list shows with no content type on the nodes with that type. I have since renamed the taxonomy, but there is still an issue.

When trying to edit the node from the admin menu I get the following error:

Notice: Undefined index: case_studies_node_form in drupal_retrieve_form() (line 750 of C:\wamp\www\ppi\includes\form.inc).

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'case_studies_node_form' not found or invalid function name in drupal_retrieve_form() (line 785 of C:\wamp\www\ppi\includes\form.inc).

I checked the database and the nodes have the correct type in the content table, and the content types table still has the "Case Studies" type.

  • Two things to try: 1. Clear your caches. 2. Maybe this link is relevant? – Malks Dec 9 '11 at 0:19
  • I have cleared my caches for sure. This link came up in my search, but I cannot even get to anything to change in the Drupal admin section. I am going to try altering the machine name in the database (after a backup, of course). – mikeyrocks Dec 9 '11 at 19:09
  • did you create this content type programmatically or via the admin UI? Drupal 6 or 7? – Sk8erPeter Nov 3 '12 at 22:58
  • When you changed the taxonomy name, have you changed the machine name too? – Tyler Durden Dec 20 '12 at 12:05

Suggestions:

  1. Make sure the module handling custom node type exists and is enabled.

    Based on case_studies_node_form callback, it's most likely case_studies module.

    If you don't know type of the node, you can load it using drush, e.g.

    drush ev "var_dump(node_load(123));"
    
  2. Make sure the module which handles custom node type defines hook_node_info() in its .module file.

  3. Clear caches (drush cc all, restart Memcached/Redis if present).
