Wiki gone after removing alias

Hi All,
We have a multiwiki setup and when we edited one wiki and deleted the alias, the wiki seems to be gone so we cannot edit it anymore and add the alias back, but the files seem to be there.
Any idea how we can get it back?


Aliases are actually stored on the main wiki (see wikis index on the top right menu). The wiki configuration you have in the wiki is just a shortcut.

What we did is to access the edit page of the missing wiki by typing the URL and then edit the alias back to the original.
