Doesn't work with an URL with @ in it

What error do you get? That URL works just fine for me, both for the URL rewriting and redirection.

Sorry, maybe I’m doing something wrong.

The page redirects to https://flipboard.com/iserotope, not
https://flipboard.com/@iserotope

(even though I’ve typed in /@iserotope

(But the permalink says /@iserotope.)

I don’t get an error. When I go to https://iserotope.com/extras, it links me to flipboard.com/iserotope, which is a blank page.

Thank you!

Oh! Do you mean it REDIRECTS you to the wrong URL? That is, the link works from “view post” in the admin, but going to the original WordPress URL results in a bad redirect?

Yes, sorry for being unclear.

When I type in iserotope.com/extras, it redirects to nothing.
Also it redirects to nothing if I click on Extras up in the website menu.

(And yes, the link does work when I “view post.”)

Thank you again for your patience.

Turns out this is an issue in WordPress core, which strips “@” from redirection URLs. I came up with a workaround for Page Links To, which is in version 2.9.6, just now released.

Thank you very much!
