I just bought Booklibrary Pro. When I go to the frontend and accept a lend request, I get this error:
Fatal error: Call to undefined function sendMailRentRequestCB() in ...componentscom_booklibrarybooklibrary.php on line 626
This is on line 626:
The function exists and looks fine, the book gets accepted and the email is sent out, I don't understand why I'm getting the error.
