Hello mozack, Thank for your suggestion, I have done this but problem is not solve. My problem is when i click one product name is 'Pocket Scale' and click 'send to a friend' mail send successfully, but when i click individualy another products name are 'Hanging Scale Type Two' and 'Hanging Scale Type one' this time when i click send to a friend mail not send successfully, see an error 'An error occurred during the process'. I think the two product name are little same so the mail is not send. because when i change the product name mail send successfully. My prestashop version is 1.2.5 final. Please give me some suggestion to solve this problem.
