Widget URL "how to disable iframe sandboxing in 5.0"

[patrickdenis]

Hi,

I have been using live map location using the URL widget but since i have upgraded to 5.0, they have restricted the url to sandboxing iframe.
In version 5.2 it is possible to disable it from the menu in Admin, General , Other , uncheck iframe sandboxing.

Where can i disable this from the configuration file in 5.0 ?

anyone ?

thank you in advance.
