(WPMU-MS) Page redirect loop on configuration

[pennymachines]

Hi,

I tried many times to configure w3all phpBB integration, without success.

This is my set-up:
PhpBB 3.1.10
Wordpress 4.7.2–en_GB - in Multisite mode

Many members are registered on my forum but none on Wordpress, so I want to share the forum membership database with Wordpress (only allowing new registrations through phpBB).

I have w3all installed (but not network activated).
I activate w3all in one of my multisites, go to Settings and get "WARNING! Wp w3all miss phpBB configuration file (or you have the phpBB config.php not well configured):"
I follow instructions for manual configuration (create config.php file in wp-w3all-config directory and type correct absolute path to it).
When I save settings I get "The page isn’t redirecting properly"

I also tied pointing to config.php in the phpBB directory, with the same result.

I should point out, I'm not using subdomains.

I'd be grateful for any suggestions as I don't have any ideas about what to try next.

Hello, what cookie setting have you in phpbb?
Have you set on phpBB ACP cookie setting
.yourdomain.com as domain for cookie
and / as path for cookie?

Logout and re-login if you change setting in this way.

I've get working fine all, months ago, in a WP multisite install test, but since it was time ago, let know if still in trouble.

Hi

Thanks for your response. Sorry I didn't have time to look at this for a while.

My cookie settings in phpBB were correct (.mydomain.co.uk path: /)

I should mention that I also tried disabling all plugins and reverting to the parent theme (Twenty Twelve).

I don't know what else to try.

Hey there,

got the issue with too many redirects as well.

This happens immediately when I log out using the Wordpress logout.
Does NOT happen when logging out using phpBB logout button.

I also could track it down to the phpbb3_xxxxx_u cookie. When I remove it the page working again. The other cookies are also not part of the problem.

My configuration is

Wordpress:
cms.mydomain.com

Forums:
cms.mydomain.com/mf2

My cookie domain settings in phpBB:
.cms.mydomain.com


Browser:
Chrome 57 beta

Thanks for taking a look into.

Best regards
Olaf

Change cookie settings in phpBB into
.mydomain.com

Logout, clean cookies, login?
