Hello!
I am having problems when using HTML-viewer and Website button.
I get the same error message for both:
Flavor contains non-whitelist URL. Please contact your system administrator.
I have populated the URL whitelist, but I still get the same error message.
The only thing that works as a workaround is creating a script button with the URL.
Regarding the HTML-viewer, it only works in edit-mode.
Thanks in advance!
Best regards,
Karin
