Recently we found an issue with google pagerank checker of seo panel, due to google domain changes.
You can fix this issue by following steps
1) Open the file in /seopanel/controllers/rank.ctrl.php
2) Find the line:
$url = “http://www.google.com/search?client=navclient-auto&ch=”.$this->CheckHash($this->hashURL($url)).”&features=Rank&q=info:”.$url.”&num=100&filter=0″;
Replace it with
$url = “http://toolbarqueries.google.com/tbr?client=navclient-auto&ch=”.$this->CheckHash($this->hashURL($url)).”&features=Rank&q=info:”.$url.”&num=100&filter=0″;
This will fix this issue.
Note: we have added this changes with latest version of seo panel 3.0.2
