There would appear to be some htaccess issues that are causing problems:
1. Dynamic Keyword insertion into the body copy, h1, title tags, description, etc.
--- This is a temporary 24 hour link
--- Look at the h1, title tag, meta description, body copy - see the "[login to view URL] "
---->[login to view URL]
2. Pagination - click on the bottom pagination
--- This is a temporary 24 hour link
---->[login to view URL]
This is a very simple custom script. Most likely this is a token and htaccess issues.
