Has anybody managed to get the plugin working? I tried to follow the RPX instructions 100% but it didn't work for me (both popup and the iframe version). The RPX control panel shows the login attempts as successful, but I cannot really login to phpBB3. I tested gmail and facebook options on default (prosilver) and custom (rockettheme) template.
I suspect it must be something with the token_url
which i might not understand correctly. I get a valid API response (through RPX test tool) but sending it to a token URL doesn't do the trick
For token_url I have used domain URL where phpBB in installed.
PS: I am using phpBB3 integrated with Joomla with RokBridge component.
