Hi. I'm having this specific error:
Fatal error: Call to undefined function wp() in /home/craz/public_html/wp-blog-header.php on line 18
What happened was I had super-cache installed and my host said it had crashed my site, which it did. So I went to uninstall supercache and my host removed the lines inserted by super cache in .htaccess
Then I got this error. What should I do? I need this up as soon as possible. I've lost about a couple thousand pageviews by now. Thanks.
