The slider doesn`t work on Wp.org.
1. Dashboard -> Pages -> Add New
2. Name your new page (let`s say Slider), then go to the Page Attributes (the same page), there is a Template menu and theoretically select Showcase Page, but there is no Showcase page in Worpress.org, but in Wp.com.
Any other ideas?
Thanks

Ok. thanks
I try to update manually, but I cant deactivate my plugins as I cant enter in Admin. It`s ok to follow the next steps without this operation?

When I try to enter in admin I`ve got this pb since I tried to update to WP 3.1:
Fatal error: Call to undefined function is_network_admin() in /home/putinaem/public_html/wp-admin/admin-header.php on line 16.

How could I fix it please?
Thank you.
