Just updated to V7 and I am getting the subject error. I have searched for this function and found references in ./pages/page-analyze.inc.php, ./class.utils.inc.php, and ./index.php. I get this error both when opening site/generator and also invoking runcrawl at the command prompt.
I also had to remove the provided .htaccess file to get this far.
Can you help?
Thanks,
Milt
