Plugin no longer working for me

Hi I love your plugin, it’s a free shining light amongst other paid for plugins that dont work as well.

I am running a new server config and your plugin has stopped working.

Absolutely this is my issue however I would appreciate your advice.

I use server side object caching (as before – the redirects worked)

I use client side page caching (as before – the redirects worked)

I use server side Cloudflare caching (as before – the redirects worked)

Now I have moved to Plesk, the only change and the plugin has stopped redirecting.

I have disabled the caches one by one and still the same result.

I can’t think of other changes. What would you advise please?

Thank you for your amazing work.

Neil
