TCPDF ERROR: Some data has already been output, can't send PDF file

Answer 1

When you have "TCPDF ERROR: Some data has already been output, can't send PDF file" it's because you have displayed something in screen. Maybe another warning.

Try to put an "@" before the function's call, that will supress the error message source

if all works fine, you know where search the error
