# cookie error when mapping domain

 * I have the exact same problem described here: [https://wordpress.org/support/topic/cookie-error-when-logging-after-changing-domain/](https://wordpress.org/support/topic/cookie-error-when-logging-after-changing-domain/)
 * I have a multisite install. I created a new site. Everything is fine until I 
   pick the domain I’ve bought for it, and then I can’t log in. I have another site
   on that install with its own domain ([http://climbtothestars.org](http://climbtothestars.org))
   and can log in fine.
 * What is the fix? It must be something simple, as the site works without the domain
   mapping and domain mapping works on another site of the same install.
 * Help!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcookie-error-when-mapping-domain%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Check if you have the following line in your wp-config.php: define(‘COOKIE_DOMAIN’,‘
   climbtothestars.org’); remove it.
