email , pdf , print button does n't work

invoice7.1 template on Phprunner v7.1
On my local pc when i press the buttons

a) create pdf

<img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=21982&image=1&table=forumtopics' class='bbc_emoticon' alt='B)' /> send invoice

c) print
It turns me back to invoice list page and nothing happend (no pdf , email or print)

I have uploaded to demo-server on spiti@valid.gr account and i 've noticed that doesnt work there too.
older version phprunner 6.2 and older invoice working fine!

anyone has any idea? ... is there anyupdated version of template?
