[democolis]

Hello,

 

I have a strange problem. When i use prestashop backend in the english language and i am going to view an order invoice under the orders tab then everything it's ok. When i use the greek language and i am trying to view an order invoice i get an error: TCPDF ERROR: Some data has already been output to browser, can't send PDF file. I tried to insert the ob_clean() command in the PDFGenerator.php but doesnt work. I am using prestashop 1.6.0.14..

 

Can somebody help me?
