I think that file is uploaded, with survey completed, but no file in the result page (when you browse result) (can you confirm that? )

something gone wrong with json parameters, and probably with the last bug : quote in title or comment field.

It's: http://git.io/XwuKyg

Patch:
Replace
$result = $this->sProcessStringContainingExpressionsHelper($result,$questionNum, $staticReplacement);
BY
$result = $this->sProcessStringContainingExpressionsHelper(htmlspecialchars_decode($result,ENT_QUOTES),$questionNum, $staticReplacement);

In classes/expressions/ExpressionManager.php

Thanks for answering this so quickly.

The above code amendment has fixed the problem.
