After 3.9 update 301 redirected sites not working

Example, https://dallasmomsblog.org/ should go to https://citymomsblog.com/dallas/.

That doesn’t make sense. Do you mean that dallasmomsblog.org pulls content via a mapped domain from citymomsblog.com/dallas/ ?

Mika-Some of the sites in the network were previously single site WP installs, before joining the “network”. The network uses a subdirectory structure, and the original site server uses a 301 redirect to point to the subdirectory. Prior to updating to WP 3.9, the redirects would point to the /dallas (or whatever) subdirectory, but now it just bounces to the primary https://citymomsblog.com domain. Thanks.

Mika-We ended up finding a solution on the redirect from the external site. We removed “www” from the redirect URL and that has fixed the problem.

# For security reasons, Option followsymlinks cannot be overridden.
#Options +FollowSymLinks

RewriteEngine on
RewriteRule (.*) https://citymomsblog.com/dallas/$1 [R=301,L]

Okay, that makes a little more sense though it’s weird…

The REASON this happens is because we’re working on making WP able to handle subdomains AND subfolders! You did a weird thing and got caught in the middle ??

I would put in my .htaccess, ABOVE the calls for WordPress, this:

RewriteCond %{HTTP_HOST} ^dallasmomsblog\.org  [NC]
RewriteRule ^(.*) https://citymomsblog.com/dallas/$1 [L,R=301]

Then you can easily have everything point to one IP.
