Error when using Keyword Tracker php file

I copied and pasted the php code in order to search yahoo and msn also into its own file on a site. There is nothing else in the file besides this script and it is saved on my domain as "ranking.php"

But, whenever I try to use the keyword tracker script, I always get an error that says:
"The request returned the following error:
Unexpected result from your server:"

On this particular keyword, the error result that was shown is: a:1:{s:7:"results";s:2:"12";}

I have tried this on a couple of different pages, by installing it on a few different domains etc., and always get the same error.

Any ideas?

Thanks

I've had the same error for some time. It seems to show a dump for Google on 4-10 keywords, after checking all automatically.

I finally figured out that if I go in and edit prefs, pull the php tracker url, and click on those dumped results, I get the correct rank.

 

Have you tried going to the keyword forums?

 

You mean here?
