Smarty-warning prints even if Smarty works

[Mathias Bøhn Grytemark]

The warning "Could not display smarty. Are you sure you have write-access to the tmp/template*-folders?"
is printed even if Smarty works.

This is because the Smarty->display()-function never returns true.

Replaced "$smarty->display() or die()" with "$fetch = $smarty->fetch(); if (empty($fetch)) die();"

+ print ($fetch);
