After upgrading to Usermin 1.330, when my users try and click the button to open their address book, they now get the following:
Warning! Webmin has detected that the program http://192.168.1.254:20000/mailbox/address_chooser.cgi?addr=&mode=0 was linked to from an unknown URL, which appears to be outside the Webmin server. This may be an attempt to trick your server into executing a dangerous command.
If your browser does not send the Referer header needed, you can turn off this check as follows :
Login to Webmin normally.
Go to the Webmin Configuration module.
Click on the Trusted Referrers icon.
Check the Trust links from unknown referrers box, and click Save.
Alternately, you can configure Webmin to allow links from unknown referers by :
Login as root, and edit the /etc/webmin/config file.
Find the line referers_none=1 and remove it.
Save the file.
I've tried everything on this message, but nothing seems to work. Do you have any suggestions?
