There is a menu entry(left end) and a page in our Turkish locale site: tr.libreoffice.org the item named YeniPage. Page url: http://tr.libreoffice.org/yenipage/
I cannot see any entry in Silverstripe admin panel(on site tree). So i cannot delete this entry and page.
infra is moving their ticketing to Redmine. Can you maybe re-enter the ticket there at http://redmine.documentfoundation.org and assign it to Cloph?
Sorry for those inconveniences, we still need to find a migration path for the BugZilla issues coming in for WWW...
the YeniPage is a deleted page - somehow the status was not correctly reflected.
To view those pages, set the filter in the admin (above the tree-structure) to "All pages, including deleted ones".
But somehow I guess there's some mixup - there are many pages with that default page title, I think I'll clear this up directly in the database....
