WordPress 4.4.1 Redirect Loop

You notice you receive one of the following errors whilst trying to browse to the home page of one of your WordPress sites after updating to 4.4.1:

ERR_TOO_MANY_REDIRECTS

This webpage has a redirect loop

This page isn’t redirecting properly

I saw this on one of the WordPress sites I manage for a local takeaway. The problem occurred after the update to 4.4.1 and had me stumped.

All other pages would load but not the static homepage. Changing the permalink structure to plain (post-id) fixed the problem but changing it back to postname made the problem reappear.

Interestingly, if I browsed http://homepage/index.php or http://homepage// (yes, a double slash) the home page would load up just fine. Weird. I’m sure a .htaccess rule would fix this but I didn’t delve in to this.

The solution?

Simple. Check your WordPress address and Site Address in Settings –> General.

Ensure they’re both lower cased and not mixed. Don’t ask me why or how this works because I have no idea.

  1. Hi!

    Interesting! I have the same problem (also static homepage) since 4.4.1. In my case I use a IDN Domain, so maybe that’s the problem (but I can’t change the domain name :-)).

    If you try: http://www.audiopädagogik.ch/ the redirect loop flashes for a second, and for some reason the last post does not appear.

    If you try: http://www.audiopädagogik.ch/index.php it works just fine!

    Weird! I guess I have to reinstall the previous WP until this is resolved.

    1. Interesting! If it’s not the case sensitivity that’s causing the issue then what you said (international domain name) also makes sense.

      1. Hi Mikail!

        I reverted the site back to 4.3.2 and the problem instantly went away. I’m now going through the changelog for the versions after, to see what change could have caused the issue. IDN domains are a pain anyway. But I had no choice. The client only had that domain name with an “umlaut” in it, so I had to use it. 🙂
