I changed config.php as you said - the language related errors 
disappeared from error.log, but the blank-page problem still exists.
Radtest works fine - I am running both Wifidog and Daloradius/Freeradius 
on the same server. I am using the servers main IP as the link between 
Wifidog and Freeradius as I am aware that the loopback interface is 
configured as a testclient in the freeradius config files.
I still think that the poblem sits with these error messages as it looks 
as PHP gets stuck and  makes not even an attempt to contact the radius 
server:
[Fri Jan 21 13:32:14 2011] [error] [client 192.168.22.93] PHP Fatal 
error:  Call to a member function getId() on a non-object in 
/var/www/wifidog-auth/wifidog/classes/User.php on line 133, referer: 
http://192.168.22.89/wifidog-auth/wifidog/login/?gw_address=172.16.15.1&gw_port=2060&gw_id=puppy&url=http%3A//www.google.com/firefox%3Fclient%3Dfirefox-a%26rls%3Dorg.mozilla%3Aen-US%3Aofficial

I had a look at the line of code (133) mentioned in the error, but 
cannot see anything problematic. My guess is that something earlier in 
the process of the attempt to login via radius is not creating a 
particular object. This seems to only happen with radius logins - 
standard Wifidog users CAN login in my setup.

thanks for your help, Mark
