I installed WP in /blog from my root and setup redirection in .htaccess and have also enable permalinks. Recently I installed a newsletter plugin that has an activation link in the subscribe back to the site and when I click after registering I'm getting a 404. I did a little testing and was able to get it to work but I'm not sure if this is a redirection or plugin problem.
Here is a snippet of the activation link that fails with 404:
Here is a tweak on the activation link that loads the page:
Simply point to the site root vs. the root/blog and I get the page. I'm not sure why the plugin is using the root/blog in the activation email. Any thoughts on how to correct this?
