Issues with 404 Redirect plugin

Hi 404 redirected plugin user, I took over the development of the plugin a few weeks back because I was experiencing many security issues and PHP notices with the plugin to the point that I learned it was about to be removed from the repo if I hadn’t stepped in. Makes sense if security measures and PHP updates haven’t been fixed in over four years. I’m trying very hard to find all the bugs, but there are a lot of – maybe too many – variables to take into account in the code. So I’m tackling them one by one. If you find a bug (or have a feature request), I’d love for you to report a full bug report if you’re still experiencing issues with the latest version of the plugin here: https://github.com/defries/404-redirected/issues So again, I’m doing my best to make this plugin fully usable again without any errors, but I only took over a few weeks ago, so bear with me. https://wordpress.org/plugins/404-redirected/ Amp incompatibilities…
