Hi RobbieNCC,
Sorry for the late response. We had some internal issues, then had to recover account credentials etc.
Anyway, thank you very much for your feedback.
Most of the users did not complain about this warning (probably because of the production php configuration which didn’t show Warnings and confused ajax calls as well).
Since we started to get more and more complains on e-mail, we have just released version 1.1 which fixed this.
