Can this not run perfectly fine without the licence field being filled in?
Well generate content won't as no licence
The latest version here (v3.7.6) works fine for me on testing on local and sandbox.
The previous versions don't work on local and only on sandbox as the code has been changed to local instead of just activating it.
It should stay as 'return true;' and not be changed to 'return nulled'
The same with '$url = localhost;' should stay as '$url = $this->endpoint and the rest of this line....'
With it as it is it will only work on sandbox and live sites and not local sites.
Only on local testing this error comes up because the nulling is wrongly done.
