This plugin will allow you to add extensions to the end of your pages. Choices are: .html, .htm, .php, .xml, .shtml and .asp.
Sadly. No support, no response to emails and no response on support forum. Seemed like a good plug in until I couldn't get the results I needed. If I get the answers I'm trying to get, I will come back and raise the review.
It doesn't change the links to the post/pages properly. Resulting in a page not found error.
