I have a few galleries on my site which were broken after the core update to 7.16. Attempting to view a gallery results in the following error message:
Notice: Undefined index: comment_node_media_gallery_form in drupal_retrieve_form() (line 765 of [snip]/form.inc).
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'comment_node_media_gallery_form' was given in drupal_retrieve_form() (line 800 of [snip]/form.inc).
I don't know any php...anything I can do?
