I was installing a different bridge for joomla and phpbb3. It got alle messed up. Neither joomla or phpbb3 would work. I couldent login on front or backend. But luckely a friendly person saw my cry for help. And that person helped me getting rid of the other bridge and opened my eyes for Jfusion. And thank god for that. Jfusion works like a charm. Sync users between joomla and phpbb3 with no worries. Im very glad for this extention. Once you tryed Jfusion youll never let it go.
