BookLibary Component Support

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:
if($booklibrary_configuration['lend_answer']){
sendMailRentRequestCB($datas,_BOOKLIBRARY_LENDREQUEST_EMAIL_ACCEPTED);
}



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.

Hello,

Please go to file:

components/com_booklibrary/booklibrary.php on line 626

and code
sendMailRentRequestCB($datas,_BOOKLIBRARY_LENDREQUEST_EMAIL_ACCEPTED);


replace to :
PHP_booklibrary:endMailRentRequestCB($datas,_BOOKLIBRARY_LENDREQUEST_EMAIL_ACCEPTED);

And for you all will good.

Thanks,
