I am the owner of the site (livepr.info) There is some thing wrong with the script ,I will soon check it out and inform you and also non of the PR checkers are showing the correct PR
Checking pagerank has been hit and miss since the 8th. Below is an article that may explain what little that is known. Google Pagerank Query
huh, this is really dream come true, It shows PR 10 for my site as well. I wish this was from Google, not livepr.
I know what happened, it happened also to my mobile Pagerank checker site http://myrank.mobi , what happened is that google blacklisted several hosting IP addresses so that they cannot access the file the pagerank scripts use to get it information. This happened with godaddy or at least in my case. I fixed after a couple of hours.. it took me a while to figure out I also thought I had PR10 for all my sites lol So basically the PR fetches its info from google, since google blocked recently all these hostings IPs then output of the resquest would be an error page, since the error page is more than xx characters it the scripts will output PR 10. Hopefully this will help several webmasters, I guess the easiest solution for many would be to change host to one that isn't blocked by google...
