FPDF works locally but not online

[system]

I have a FPDF output which works perfectly locally but there is problem online.

The error is:

Fatal error: Uncaught exception ‘Exception’ with message ‘FPDF error: Some data has already been output, can’t send PDF file (output started at /home/wa/public_html/razpis/baza.inc.php:1)’ in /home/wa/public_html/razpis/fpdf.php:271

The error message indicates you have output on line 1 of - baza.inc.php

You would need to find what that output is and eliminate it… Some common possibilities -

1. The file has been saved as a UTF-8 encoded file, with the BOM (Byte Order Mark) characters. If so, save the file without the BOM characters.

2. You have some characters in the file before the <?php opening tag.

3. You have some php code on line 1 in the file that’s producing output.
