Since some time (not sure since when) the Authentication
setting in Client communication
(described here: https://www.phpbb.com/support/docs/en/3 ... al_client/
) section, in admin panel, gives a white page. The URL is: http://domain.com/adm/index.php?sid=ea3 ... &mode=auth
The Email settings and Jabber settings is ok.
If i need to provide some php and board version info please let me know.
