After restoring a wiki backup I'm having a problem with namespaces. Namespace "XYZ" was not defined in my old server's LocalSettings.php, the pages were added just by typing in the namespace before each new page name ie. XYZ:Pagename. Now on the new server, after restoring the backup, all pages in namespace XYZ don't exist. When a link to a page in namespace XYZ is clicked, the create new page is shown. As I said before, I fear this was caused by not specifying the namespaces in LocalSettings.php on the old server. Adding a namespace declaration in the new server's LocalSettings.php doesn't fix the problem either. Any ideas? Thanks!
