[Mediawiki-l] MediaWiki:Licenses

[Uno P2Pforum.it]

I've got a problem with the page MediaWiki:Licenses

Some time ago I've deleted some records from the DB and maybe one of them
regarded this page, now when I visit the page MediaWiki:Licenses I get this
error:

There is currently no text in this page.
You can search for this page title in other pages, search the related logs,
or edit this page.

If I try to edit the page MediaWiki show me this error:

You tried to edit a section that does not exist. Since there is no section,
there is no place to save your edit.

How can I resolve this problem?

Thanks
