I've just installed the last version of phpBB and of this plugin to make some tests for future usage.
I think I installed it well since everything is OK in the config table : http://puu.sh/X4NY
By the way, my wordpress folder is /www/wordpress/ and my forum is /www/phpBB3/
I tried creating a user from both wordpress and phpBB, they won't sync to each other :/
Any help will be pleased, thanks :)
