Hello,
when a "Filter Actions" is defined which includes one or more "Blocked file extensions" entries, this setting is not shown on overview screen at
Web Security » HTTP/S Profiles -> Filter Actions.
The complete list of "Blocked file extensions" is just missing, not a single blocked extension is shown.
When the same "Filter Actions" includes one or more entries in the "Always block these URLs/sites" list, all configured "Blocked file extensions" are shown on overview screen.
Regards,
Manuel
