Error 500
Assuming it hasn't been fixed by the time you check it out... take a look:
Per other suggestions that I could find, I created a phpinfo file (http://conspirepedia.org/tiki/phpinfo.php) and a redirect page (http://conspirepedia.org/tiki/tiki-setup.php). Neither worked. I've moved and renamed the folder (even to a different domain on the same host) and checked permissions (all look OK - 777 or 775 or 755).
Any ideas?
