Keep being redirected to the home page

Here is the output when running https://mathdatasimplified.com/?redirect_to=random&rutpdebug=2

Debug mode is on. We will only display the resulting URL, without redirecting.

We use redirect_to=random.

So it seems like it should redirect to that page, but it doesn’t. I use W3 Total Cache. Maybe that can cause the problem?

Actually somehow it works now! It may be because the new plugin takes a long time to load.

I think that is indeed a caching problem. Another plugin or a service like Cloudflare caches the first redirect and later skips the database query.
