We have a node type with permission to create new nodes for guests. When we try to create a new node of this type as guest we get the following error:
EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 7844 of /var/www/miwula/includes/common.inc).
In watchdog I get only the same message and nothing in apache's log.
I created a new node type with no other fields and with create permissions for guests too. Same problem.
I have no idea what I can do.
