Joomla error after uploading

just copied my joomla site folder to godaddy domain and when i visit the home page i get this error Fatal error: 开发者_C百科Call to a member function getDefault() on a non-object in /home/content/88/8216088/html/public_html/includes/router.php on line 123

any help ?

After some Googling, I've found a similar thread at http://forum.joomla.org/viewtopic.php?p=2441892. Since this sounds like a bug, I don't really think we will be able to solve it here.

The best thing you can do now is to try to help Joomla! developers with reporting the issue and following their instructions for debugging and solving it.
