Redirect loop issue after 3.9 upgrade

I have the same problem. If I type in https://www.realtyparadigm.com/shop it redirects me to my homepage. But if I type in https://realtyparadigm.com/shop, it takes me to the proper place. This is only after upgrading to WP 3.9. However, both my siteurl and home values are https://realtyparadigm.com, that’s what’s been suggested doesn’t seem like my issue. All my add-on site work fine either way. It’s just my main site that is acting like this. Any suggestions?

Well, everything worked fine before I updated to WP 3.9, so I don’t really want to mess with changing anything, except for what’s wrong with 3.9. Plus, I’m running wp multisite, and remembered following careful, precise instructions setting up all the DNS settings, so I’d rather not mess with them.

My host suggested adding this to my .htaccess file:

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

That seems to have worked. But is this the proper way to do it? I didn’t change anything other than updated to 3.9, and I’ve never had this problem before. I’d like to fix it for real, and I feel like I’ve just put a bandaid on it.

That rewrite worked a charm for me. Thanks.

The urls work with or without www. I’m very pleased.

Does anyone has a rewrite rule for nginx, that will not break domains mapped through wildcards?

got the same issue trying to upgrade robadadonne.it!
In my case it was simply solved by (re)saving permalinks structure (wp-admin/options-permalink.php).
Have you tried this?

resaving permalinks did NOT work for me. i did it through the backend.

mkdev – please make your own post.

Everyone: If the two fixes (editing the DB and saving permalinks) does not fix your site, please make a new thread ??
