Canonical Issues with Wordpress

[RunningInTheRain]

Hi all,

I have just started using Wordpress SEO by Yoast and still having a hard time correcting my Canonical issues for all posts with a .html at the end.

The pluggin allows you to add a '/' to the end for canonical issues, but just for pages, not posts.

How best in Wordpress to make my post change from .html/ to .html. I really don't want to go to the hassle to make each URL a new 301 redirect in my .htaccess.

I hate the .html, but if they are going to stay, how can I make sure I get the .html/ link juice back to them.

Many thanks!

Are you using a plugin to append .html to the end of WP pages? If not, I'm confused as to what html doctypes are doing on WP

In my permalink structure page in settings, I have it set as follows:

Custom Structure: /%postname%.html

I know, don't ask why I set it up this way years ago. But thinking how best to remedy the solution without hurting my traffic.
