I have both the Blue and Modern themes installed. Last night I changed from Blue to Modern by changing “blue” to “modern” in the backend under Configuration/Design.
After I did that, any page (front or backend) only displays the text:
Fatal error: Call to a member function children() on a non-object in /home/hanwei/public_html/app/code/core/Mage/Core/Model/Config.php on line 177
Can anyone point me in the right direction here? Thanks!
