Actually,
I have a Wordpress 1.5 blog up on my other account and I was able to install this plugin clean with no modification to the .php file, ie it still reads:
$awstats_dir = '/var/lib/awstats';
$awstats_site = awstats_getsite(get_settings('siteurl'));
i dont know if this is important info, but I am adding it since it might be worth considering for whoever can help me...:-)
the original code included with the plugin didnt work for my wp 2.0 blog, though, so I tried this :
$awstats_dir = '/home/*********/tmp/awstats';
$awstats_site = awstats_getsite(get_settings('siteurl'));
and it wont work either. Ill throw in a gratuitious smiley for good measure!
