Cookie Confirmation Type Opt-in conflicting with ShortPixel Adaptive Images plug

Hello,

The users of ShortPixel Adaptive Images plugin reported an incompatibility with Ginger EU Cookie Law, particularly with the setting “Cookie Confirmation Type” Opt-in.
ShortPixel Adaptive Images relies on an ob_start callback to do its job. When this Ginger setting is on, the Output Buffer that is received by the callback is empty. Do you know what could be the cause and how can we fix it so the users of both plugins can use them together?

Best regards,
The ShortPixel team.
