I have a client WP website which has the following permalink structure: /%year%/%monthnum%/%postname%.html
The .html suffix is there to insure compatibility for a Blogger to WP redirection plugin which has outlived its usefulness. I want to now change the permalink structure to just %postname%.
But I want to avoid creating thousands of 404 errors for existing internal and external links. What is the best way to modify my htaccess? I’m not sure if this requires a regular expression redirect or a rewrite rule. I’m an .htaccess novice and would really appreciate some steering in the right direction.
