Question about Replacement Messages system variables

Hi,

I'm facing an issue with Replacement messages, specifically FortiGuard WebFiltering >FortiGuard Warning Page

In the html source, I see the Proceed button href is generated with the '%%WARNINGLINK%%'

The thing is while on 90D, that variable gives the full uri of the page being warned, but on the 500D it always give the root page with the uri '/'.

Both 90D and 500D are running os 5.6.4

On 90D

On 500D, the same action

Is this a thing of the 500D? Can we somehow manage those system variables?(I guess not)

Can Fortinet do anything about this?

Appriciate any answers or replies.

Thanks.
