So Please Please as early as possible.

It looks like you're outputting a binary string (a PDF, perhaps?) but you're not setting the proper HTTP header.

What happens if, right above line 81 in the code above, where you call Output(), you do: header('Content-Type: application/pdf');

[Dani]

I can't see how that would be the case, hmm. Can you take a screenshot of what it looks like now, with the Content-Type header specified?

[Dani]

Can you also please provide your updated code. I want to make sure you added the line properly. Did you make sure there's a space after Content-Type:?
