I decided I'm tired of whatever this weird problem is. So I went into spider.php and changed line 94 from
Code:
$relative_script_path = '..';
to
Code:
$relative_script_path = '/Library/WebServer/Documents/admin/phpdig';
and that seems to have gotten everything working. Still dunno what was wrong with '..' since it seems like it should, but whatever.
Thanks for all your help. This was driving me nuts too.
