I am getting the following errors when I attempt to produce a pdf.
Warning: Cannot modify header information - headers already sent by (output started at /home/content/t/r/a/transconvalue/html/propinsp.php:7) in /home/content/t/r/a/transconvalue/html/fpdf.php on line 1017
FPDF error: Some data has already been output, can't send PDF file.
From what I have been able to research, the header issue is generally caused by blank spaces, but I can't determine where they are.
I'm at a loss on the some data has already been sent. Thank you.
