If you go to my blog, you will see everything is normal. But, if you try to click on one of the headline titles, the links are broken. This happened recently when my hosting service was temporarily suspended. Working: http://www.jwpincorporated.com/blog/index.php Story view broken: http://www.jwpincorporated.com/blog/2007/05/30/please-please-please-tell-me-why-gas-pumps-do-this/ I will give someone a PR4 link on the blog for 3 or 4 months to fix the issue. Thanks.
It would appear that the .htaccess file is not configured properly or has been reset. If you want to post it's content here or pm it too me I can have a look.
Easiest way to fix it would be login to wordpress. Options-Permalinks and select the top option "default" Apply that then check site. Then go back and select "Date and Name Based" then apply. Let us know if it works.
