1. I created 2 wikis without parent/child relation.
2. Went to the site and their respective links are ok.
3. Went back to the wiki editor, edited one of the wikis, and specified to be the child of the other.
4. After visiting the site again, the link to the child wiki is screwed up and points to an empty form with the title: "Wiki page you are looking for does not exist. Feel free to create it yourself". In some cases (although I did not understand when/why) the error message is: "It seems we can’t find what you’re looking for. Perhaps searching, or one of the links below, can help".
5. I deactivated all plugins and changed the theme to "TwentyEleven", but the problem still persists.
Could you help me?
