Thread:Project:Support desk/lost some page./reply (2)

This may be the crux of the problem, thank you.

These pages should not belong MediaWiki namespace, and this namespace MediaWiki should not be the name (should be maintained his original name).

I guess these pages originally been classified in a certain category, then the MediaWiki namespace has been changed to use the same word.

If I could change back to the mediawiki namespace, should be able to solve this problem.

But I do not know how to change the namespace name, someone can teach me?
