Just tried doing a check and got this spat back at me: Warning: file_get_contents(<path to the advanced script>?se=g&d=50&l=&q=<query string>&u=<url of site to be ranked>&key=<google api key>): failed to open stream: HTTP request failed! in /home/.sites/28/site1/web/tools/keywords/functions.php on line 112 Presumably this either means the advanced script couldn't be found, or Google didn't return a page. Any chance of adding some error handling so that we get more enlightening responses? Might reduce the number of support posts you get...
Shawn, Advanced usage script was indeed in place, it seems to be working OK now so it must just have been a brief outage on my webhosting account causing it.
