Some of my sites have no PR anymore. The toolbar is grey, not even 0/10 in white. There are some sentences starting with 'Links' on my main page. A few sites still have the old PR and when I check all of my content sometimes there is a PR and sometimes it's all grey.
I think there is something wrong with the toolbar b/c all of my keywords still appear at #2 - (www, -sj and -fi)
