Recently upgraded www.suffolkbasketball.net to Joomla! 2.5 running K2
Everything has been fine until today when I try to access the site I get:

Fatal error: Call to a member function load() on a non-object in /home/suffolk/public_html/components/com_k2/views/itemlist/view.html.php on line 40

line 40 loads the category id ( $category->load($id); )

When I try to access the site's backend admin area I get a 404 page not found error. My host tells me PHP is working normally, I can access files via FTP & cPanel.

Any ideas? Thanks in advance.

OK - a bit embarrassing that one! I somehow managed to move the "Admin" folder from root to another folder. Moved it back and everything works fine - strange that!!

Hi, I just received this message:
Fatal error: Call to a member function categoriesTree() on a non-object in /home/scott/public_html/administrator/components/com_k2/views/items/view.html.php on line 124

Any ideas? I need help.

Can you be more specific? What versions are you using? Where did you get the error? Front-end or backend? module or component ( and what view )? Do you have any K2 related extensions installed?
