WordPress MU

I've been scouring the forums looking for a solution for the wp-signup.php going into redirect loop. I am hoping that I just overlooked a solution for this.

I upgraded from 1.5.1 to 2.7 of a subdir installation. 1.5.1 has been running great, but I felt that it was time to upgrade.

I've checked the error_log, and I don't see any errors when the redirect loops happens.

Here's the blog: http://achillesblog.com/wp-signup.php

Has anyone been able to resolve this issue?

thanks,
Dennis

I had the same problem - clear your cookies and saved sessions in your browser. works like a charm!

pastorjack - that doesn't help unfortunately. Still in redirect loop. Please try: http://achillesblog.com/wp-signup.php

Are signups enabled in the backend?
Also, did you modify the signup page?
Have any plugins, like extra fields on signup?

VentureMaker:
"Allow new registrations" is set to 'Enabled. Blogs and user accounts can be created'
The wp-signup.php has NOT been modified.
I've tried removing all files from wp-content/mu-plugins and wp-content/plugins directories, and then accessing wp-signup.php from a browser. That didn't help either..

Any other things that I can try? thanks.

http://achillesblog.com/wp-signup.php I see another error, not loop now.

VentureMaker - I put some trace statements into the wp-signup page trying to see where it's bombing out.

This is where it is dying:

if( $current_blog->domain . $current_blog->path != $current_site->domain . $current_site->path ) {
        wp_redirect( "http://" . $current_site->domain . $current_site->path . "wp-signup.php" );
        die();
}

So, you're on WPMU 2.7, right?
Do you have the following lines in your wp-config.php?

define('DOMAIN_CURRENT_SITE', 'yourdomain.com' );
define('PATH_CURRENT_SITE', '/' );
define('BLOGID_CURRENT_SITE', '1' );

Yes, I have those three lines in wp-config.php

Try adding these lines:

define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');

venturemaker - yeah, thanks for the suggestion, but that does't help either.. I am getting really bummed out by this upgrade.

I think I figured out the problem.
wp-signup.php fails on:

if( $current_blog->domain . $current_blog->path != $current_site->domain . $current_site->path ) {
        wp_redirect( "http://" . $current_site->domain . $current_site->path . "wp-signup.php" );
        die();
}

$current_blog->domain: achillesblog.com
$current_blog->path: /
$current_site->domain: AchillesBlog.com
$current_site->path: /

I changed the $current_blog->domain to AchillesBlog.com in the database, and the signups are working. I felt squeamish changing the value in the database directly, but I hope this fixes it.

Looks like all blogs' domain column is defined as: achilesblog.com I am wondering if I need to change all of them to be "AchillesBlog.com"

Any suggestions?

even I am having the same problem when i auto upgraded from 2.7 to latest version..it was working finr

and from yesterday its getting in redirect loop

plz suggest how it can be solved............

I am having the exact same problem after installing MU from scratch :(

http://donewrong.com/wp-signup.php?new=donewrong.com

For me it worked with this correction in wpmu_settings.php (lin 117 approx):

It fails at obtaining $current_blog as $domain is incorrect, instead I use $current_site->domain

if( !$current_blog ) {
       $current_blog = $wpdb->get_row( $wpdb->prepare("SELECT * FROM $wpdb->blogs WHERE domain = %s", $domain) );

Instead it should be:

if( !$current_blog ) {
       $current_blog = $wpdb->get_row( $wpdb->prepare("SELECT * FROM $wpdb->blogs WHERE domain = %s", $current_site->domain) );
