@miss_amylee did you solve it? I also removed ending "?>" in plugins/to_pdf_pi.php

I'm using latest codeIgniter, 1.7.2

The error just means that something has been printed to the browser before a call to the header() function. It is almost always a carriage return/whitespace after a closing php tag. Codeigniter core files come without closing PHP tags, so check any files you've created yourself or downloaded from other sources.

should I check all the controllers I've created?
I've checked only:
- controller_test.php (which has the generate pdf function)
- views/testpdf.php (which has the html)
- plugins/to_pdf_pi.php

and none of them has a whitespace char at the end. I tried also removing the ending "?>" from plugins/to_pdf_pi.php as stated before
