I had successfully installed WP-united on a domain with WP 3.7.1 and PHPBB 3.1.12. PHPBB embeds nicely in WP-united and the login is synced.
Now I am trying to move my site to a new domain name. I did a full migration by moving both files and database to the new domain for both WP and PHPBB. I used UpdraftPlus and Search-Replace-DB for WP, and bigdump for PHPBB to help me move. Then updated server and cookie settings in ACP.
So in my new site, everything looks and seem to function just like the old domain, except the logins are not synced. By this I mean, sometimes I am logged in to WP or PHPBB only, and on other times I cannot logout after repeatedly pressing logout. I've tried wrestling with this for over a month and I'm guessing it has something to do with the cookie logins. So just to give a little more info, here are my settings:
Cookie domain: .domain.com
Cooking name: make_up
Cookie path: /
Cookie secure: Disabled
Domain name: http://www.domain.com
Server port: 80
Script path: /forum
Does anyone knows how I can debug and solve this problem? Or if anyone knows how to solve this, then I'll compensate you for an hour of work to fix this for me.
