Why is WordPress Multisite redirecting to wp-signup.php and how to fix it?
I have recently set up a second blog on my WordPress multisite. The primary blog on the Multisite is
www.example.com, and the second blog I have set up two days ago is
Unfortunately, when going to
www.example2.org, WordPress redirects to
On the same server, I have set up a corresponding test Multisite, with
test.example.com being the primary blog and
test.example2.org the second blog. It is working without a problem.
wp-config.php settings are the same for both the test and the live Multisite, so that wouldn’t be the problem. I’ve also verified that on the live Multisite I have
www.example2.org correctly set in the
wp_blogs table, and also it is correctly set as
https://www.example2.org on the
home rows of the
wp_2_options table (the
_2_ part corresponding to the blog ID on the Multisite).
I would appreciate any suggestions on why this redirect is happening and/or how to resolve it. I don’t even know which file is issuing the redirect (I don’t think it’s
wp-signup.php) so I can’t look at the relevant code to debug it further.
