'Falel error: Call to a member function get_results() on a …'

Hey all,

I have a page set up that allows logged in Administrators to search for search terms that have been entered. I’m using AJAX to do this, so the results are gathered on a seperate page for display.

However, when I search the I’m being given the falel error ‘Call to a member function get_results() on a non-object’. I commented this line out, and then was told ‘Call to undefined function __()’, and then ‘Call to undefined function get_bloginfo()’.

So it appears that for some reason this page cannot see the rest of WP. Has anyone experienced this before, and if so, how did you slove the problem?

Thanks.
