It work fine on my test, so there is something wrong elsewhere in your phpBB avatars configuration?
htaccess that lead to not load the phpBB avatars in WP?
The two users on my test, are resulting in WP (because they have login or have visit WP side), and have a custom avatar in phpBB.
Of course if they were not added in WP, default WP avatar would be displayed instead.

I found out that some users directly log in into http://<website>/phpbb instead of http://<website> (login widget) could that be the problem?

hi, yes of course: if an user login into phpBB only, it is normal that is not recognized into WP by the plugin wp-whos-online :
this because it search for users online in WP, not in phpBB ...
we'll go to add this feature into WP_w3all.
Online on WP, phpBB, sum of both.
Can't be precise about when it will be added! But will be added as soon will be possible.

This feature about online users, and the complete profile fields integration between phpBB and buddypress, are the two queued most important additions to be added.

Ok how can i prevent that users will log in like that?

Is there a way to force the login only through the the w3 login widget?

Also when i user type in the wrong username/password in the W3 login widget he is redirected to the forum and gets:

Login

You have specified an incorrect password. Please check your password and try again. If you continue to have problems please contact the Board Administrator."

and gets the login screen from the forum.

Ok how can i prevent that users will log in like that?

the fact you'll force a login done in WP side, do not change the fact that if after, an user go into phpBB side (and is not in iframe mode) will not be recognized by the way by the plugin you use (because it do not search for users logged in in phpBB database, where users sessions are updated while an user visit it). The fact that you login users only in WP, not change nothing. In iframe mode, the user update ever at same time WP and phpBB databases, and in this case the joke work.

Unfortunately, the unique way to resolve would be to add the feature about logged in users into wp_w3all, that will be done as above explained, or edit the plugin code you use to search also for phpBB online users, into phpBB db.

ps i realize that the login widget, will be on next version maybe changed to point to WP login, and not phpBB. It was born in this way from very first version, and needed in this way for how the plugin was working, but now it not make too much sense to continue in this way.
The login widget code will be updated to point to WP login.
