Redirection causing issues

Hello,

I download Rank math and updated a blog post with a different URL….

I put the new URL into the redirection from the old one.

It caused that blog post to throw a 500 internal server error. I contacted Siteground, who could only see that it was the Rank math plug in.

They deactivated the plug in and my post came back.

Then I tried to turn the plug in back on and trash the redirect, but even then it still shows the blog post with a 500 error.

I can only get rid of this by deactivating rank math. I am enjoying rank math so I’m hoping there’s something that can be done.

I’d love to know what I’m doing wrong with the redirect as well…
