Issue: Invalid Tag Specified

Fixed for the next build. This occurs when you have not yet created the Header namespace and you try to Add New Namespace (assigning it as header should work fine).

In admincp/vaultwiki_namespace.php, find (all):
Replace each with:
When you make this change, a new field will appear in the form. This field is required.

Sorry, posted to quickly. Applied the file edits to the two occurence and saved but no difference.

Then tried with assigning it as header should work fine and i could create the namespace but then it created another issue.
Now the wiki is not showing on the forum ( though the Wiki button still works ) but I see two Wiki pages on the Special page.
The previous posts are showing up as orphaned............ poor posts..............funny on the Special page that was previously blank..

Your Header namespace doesn't look like it was assigned as the "Header namespace". Check the namespace functions form.

The edit I gave above was incorrect.
Should be:

That did not work either. I should clarify, I can now see the bits line but still same error.

Okay so what value are you entering for "BB Code Tag Name" (right below the bits line)?

I was creating a namespace for the wrong reason, I think. What i wanted was a space to hold chapters for books, so the Books
forum was not clustered with chapters from multiple books. What I needed to do was create a sub forum under Books using Forum
Manager. Is this correct?

Is there a way to stop posts in the /Books/Chapters subforum from showing up in What's New?

Now whatever I have done with namespaces the Wiki no longer shows as a forum section on my vB forum.
It is turned on. The posts are there. How do it get the posts and Wiki forums.sub forums to show?

Technically, either option should work. Personally I also prefer to create the chapters in a separate namespace.

If the namespaces aren't appearing in the forum list, make sure the "Show Namespace in Forum Bits?" setting is set to "Yes". Also make sure the Display Order is not 0 for them or your wiki section.

As for stopping them from appearing in What's New, there's not really an option to do this at the current time (unless you want to disable search entirely for your Books). If you know a little PHP, you can add the book forums to the search's exclusion list.
