Error: Cookes are blocked – Multisite – 2 sites work – others do not

Go to the Network Admin page. Select Sites and select “Edit” on the site that has the problem.

On the Settings tab, look for the “Siteurl” and the “Home” setting. What are those URLs?

Basically, when I load your problem site, I see that it’s setting a cookie on an “sfnet.org” domain, which is incorrect. So, find and fix the domain, and the test cookie should work properly.

I decided to create a fresh install of multisite on Bitnami and I’m having the same problem. I have added two urls to multisite, base-url sfnet.org and my additional gregorigroup.com. I can login into admin on the base url but not on gregorigroup.com.

My settings are as follows for gregorigroup.com

Info->Site URL = https://gregorigroup.com
Settings-> Site URL = https://gregorigroup.com
Settings-> Home = https://gregorigroup.com

Thanks for any help you might provide.
Best,

@wgregori Make a PHP file in the /wp-content/mu-plugins directory. Put this code in it:

<?php
add_action( 'muplugins_loaded', function(){
	global $current_blog, $current_site;
	if ( false === stripos( $current_blog->domain, $current_site->cookie_domain ) ) {
		$current_site->cookie_domain = $current_blog->domain;
	}
});

See if that helps.

Thanks for the effort but it didn’t work… I put the file in
/opt/bitnami/apps/wordpress/htdocs/wp-content/plugins

Restarted all services and then tried https://gregorigroup.com/login and got the same Error regarding cookies being blocked.

I may have to just run separate servers for all my sites… hard to believe that this will not work… Fresh multisite image install, no additional plugins two URLs… base url works and any subsequent URL fails to allow admin login…

THanks for any additional ideas.

I put the file in
…/wp-content/plugins

I said “/wp-content/mu-plugins” for a reason. MU plugins are must-use plugins. They load automatically. The plugins in /plugins do not.

Samuel! I can’t “friggin” believe it… that worked. Thank you so much. I can’t believe this isn’t a more widely talked about problem.

Thanks again.
