I got this error message. Not sure at what point in my wanderings through the site map to create a new page that it occurred. But following this message, I have been unable to add content or edit content that currently exists.

Fatal error: Call to a member function getThemeID() on a non-object in /home/hardgrov/public_html/utahalpaca.com/concrete/models/page.php on line 1026

Please help with this issue as I am currently unable to make any headway with creating my website.
