Hello All,

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

Anyone can help me to solve this issue.

Hi Sino Thomas
Try to add ob_start() at the top of the page or ob_end_clean() before calling the output function.

Did you create a custom Sugarpdf for rendering that custom pdf?
Eventually your code is echoing something which cause such error.
Maybe a blank line before the tag <?php.
Take a look at this article in order to understand how to debug the possible issue within.
