I recently changed the permlink of our website and all previous external links, especially from search engines, gives "Error" page not found.
I reasearched deeply and found out that, when I removed the /month/ and .html from the Not found_ url and replaced it with a trailing slash(/), I worked fine, and I have over a 1000 post with this issue.
How can I probably use any redirection plugin/regex to sort this.
See example links here:
How can I do this for over a 1000 post in one redirection?
Thanks as I expect your reply.
