PayPal Error

[haylau]

using 30bees 1.0.7 and 30bees paypal module 5.3.3

Just testing sandbox at the moment but we get error message of "Error(s) occurred Invalid request - see details"

There is no way to see the details.

Now, I have narrowed down the problem. It is PHP related. Works fine on versions of PHP upto and including 7.0 but get the error message on PHP 7.1 and 7.2

Is this likely to be a sandbox incompatability or generic problem with the module? Will it be fixed soon?
