I’ve not been able to understand how to fix the following problem.

1.) I installed SSL on my WordPress site.
2.) I used Really Simple SSL WP plugin to make sure all none secure URL’s are redirect to secure HTTP URL’s. It all worked perfectly.

However, after those changes, I noticed that site is highlighting some 404 errors for some external links.

So what happens is, some posts are pointing to external sources, even though the external link does not have HTTPS protocol, but is using HTTP (in wordpress editor), when I move my mouse on to the URL from the front-end of the site, I can see the same link with HTTPS, not HTTP. From what I understand this is from the plugin settings.

Problem is, when someone click on such link from the website, he/she is redirect to a page as this: https://www.steam-engine.org/batt.asp?b=AW_IMR_18650&mah=1600&c=15

It’s because we’re sending user to a secure URL, which in fact is not secure, due to the way Really Simple SSL plugin works.

Is there a fix, or anything I can do to fix these type of links manually?

I’m on NGINX server and can’t remove this plugin and need it for 301’s.

Thanks.
