If you’re using git to version Caddy configuration, you can use a pre-commit hook to test it, ensuring that you’ll never have invalid configuration. That’s what I do.

caddy validate

There’s some extra command args that may be necessary but that should be an adequate first step.

Hopefully the new maintainer can get releases going again. It’s a great extension!

If you’re talking about the extension that looks like an R with a green arrow, the author passed away a couple years ago. https://github.com/einaregilsson/Redirector/issues/329

The repo has a new maintainer but there’s been no new releases since the maintainer doesn’t have access to the extension release pages. No surprise that a MV3 version hasn’t been worked on.

It still works on Firefox, though.
