Problems with Dean’s Permalinks Migration after WordPress 2.7
I updated to WordPress 2.7 when it was released and on the surface everything seemed to work just fine. Then today when i clicked a old link to one of my wordpress sites i got a 404 message.
It turns out that Dean’s Permalinks Migration plugin stopped working after WordPress 2.7 (i assume at least, i didn’t do any research about it). You use Dean’s Permalinks Migration plugin to do a 301 (SEO friendly) redirect from your old permalink structure to a new one.
I used /year/month/day/post-title before but i wanted to change to just /post-title and Dean’s Permalinks Migration plugin worked great. But as i said before it stopped worked after we installed WordPress 2.7.
The solution i found was to install another plugin called Redirection that is used to do all sort of redirects in WordPress. After i installed the plugin i just added a regular expression redirect like this.

This means something like redirect any url that looks like /digits/digits/digits/text to /text. The $4 means to grab the text from the last * in the source URL.
Hello, I don´t know for sure, but i think that i have the same problem that you did, could you visite my site and take a look?

I just installed the Dean’s Permalinks Migration plugin, and all my pages, except the index page, became broken links, and I don´t get to fix it.
thank you.

I had the same problem on my blog in this link and this helped me get this sorted – thank you so much!
Does this still stand true? I’m trying to get my permalinks changed once I installed Dean’s things went screwy….
