Do you know for sure that web sites "are" linking to the PR0 site/pages.
If not... you can not have PageRank if no links are pointing to it.
If links pointing to it... then a possibility of a penalty, but check AllTheWeb.com to see if inbound links are there before coming to the second conclusion.
domain 1: index-page: PR4
other pages: PR1
links page: PR4
domain 2: index-page: PR0
other pages: PR0
links page: PR4
The links pages on the different domains are exact copies. They have exactly the same PR. Everything is similar. Design of index-page & other pages. Just the actual content (tekst & images) is different. Different keywords ofcourse, different tekst in tags, different images. However, the images, tekst, etc are placed in exact the same places. Design is same.
Go to Google (PR10) - now type in your URL - if PR10 at your site this is a toolbar problem - so download the new version 1.1.70
If not the problem, and:
If content is (viewable text on the page) different on each of your sites, then you will want to check links from your site to another site.
See if any are PR0 as well - if so remove your link.
