esyndicate pagerank.inc.php fix

[fcmisc]

Does anyone have a fix for the pagerankchecker on esyndicate when it doesnt work?

I've tried two fixes:

http://forums.digitalpoint.com/showthread.php?p=6495399#post6495399

http://www.esyndicat.com/forum/about9559.html

But can get neither to work.

Cheers,

fcmisc.

here's the original file, all I ever get is pagerank zero, even for google.com
