I just completed an upgrade from WordPress 2.2 to 2.7.1. I used the Customizable Permalinks plug-in set to year/month/date/name in version 2.2. When I upgraded to WP 2.7.1, I found that I get a redirection loop unless I revert to the default setting for Customizable Permalinks. I tried the Permalinks Moved Permanently plug-in but discovered it's only good up to WP v.2.6.
Help! I have bunch of dead links on my site and have lost all of my SEO value.
