Hi,
Thanks for contacting us here about this extension.
Sorry for the late response, delays in processing support are usually extended outside the business days
Failed to display rating. Error: "Unsupported operand types: string / int"
I'm sorry, but this forum is only for pre-sale questions, for all technical requests please drop us a ticket
(Menu Support > Support ticket).
Our developer in charge will take a look at that.
Cheers,
