Hello,
when I activate the "Web Secutiry -> HTTP/S Profile"-mode a default filter actions exists automatically with the name "Default content filter block action". When I delete this "Filter Action", even if it is not used in any "Proxy Profile", the Web-Proxy did not work anymore.
The proxy settings page in WebAdmin shows an error and no further settings are possible. Only a "Factory Reset" helps.
Regards,
Manuel
