[TYPO3] pdfgenerator produces wrong file

[Michael Christensen]

Hi list!

I have a problem with the pdfgenerators (I've tried pdfgenerator2 as 
well as nc_pdfgen and the same problem occurs).

I can include the link on my page, but when i press the link it 
downloads a file named index.php - if I try to rename the file to pdf, I 
  see, that it's got pdf-content and looks good, but the file i get 
downloaded is a php.
When I try to download the pdf from Safari, it works - but any other 
browser I've tested, downloads the index.php

Any ideas?

Thanks in advance!
Michael
