I can now confirm that the problem is fixed in version 3.7.14

Thanks to the plugin author for a fast fix , well done

Getting pro version now ??

Lets hope the plugin author is aware of the issue and will release an update shortly.

Tick Tock

Same problem here,

Array ( [Warning] => [Error] => Invalid appsecret_proof provided in the API argument )

Looks like dev have to come with a update to fix this problem, nothing that we can do on our side.

Was thinking about buying the Pro version, but this kinda put a damper on the buying mode. Will reconsider once this gets fixed, its a good plugin when it works.
