Hi
I'm starting a new project where I have installed the latest hikashop version with joomla 3.3.4 in a fresh empty website.

I create a product with a file that is Free download and when I go to the product page and click on the link to download, it returns an error and not the file (in the frontend).

Thank you for your help

Hi
I have removed the maintenance mode, you can access the website

error reporting to "none" and still the same issue.
Hikashop is the first component installed and the only one used in frontend for now, on a fresh joomla 3 install

May be a server problem ? If you have an idea

thank you for your help but this does not work
Error reporting = none
Gzip compression = No

and still the same like you said : the content of the file output directly

For information, I have other websites on the same server with also some ZIP files that works correctly.
I also have tesed with a PDF file on my product "theme"2, and the problem is the same.

If you need an admin access let me know I can give you this per email

yes it's in French

no problem, you know that I'm french too , but I don't see any french in this message lol

unfortunately this does not work. But, as I knew which file to edit I have made some tests and found a workaround.
I have tested another code that I know it works by my side, and it was also not working.
What I had to do is to edit the file
administrator/components/com_hikashop/helpers/helper.php
with notepadd++ and convert it from UTF8 to ANSI
once this file is ANSI encoded, the download works ! (with the original file.php)

Please check by your side if you can do something for the next version to fix this

I know that this not really related to hikashop, I was hoping that you had more ideas than me about the problem

1/ I have reinstalled hikashop (over the existing to overwrite my modifications) :
the problem is there again

2/ opened classes/file.php in notepad++ :
the file encoding was on ANSI, I converted it to UTF8-nobom
>> still the problem

3/ opened helpers/helper.php in notepad++ :
the file encoding was on UTF8, I converted it to UTF8-nobom
>> now it works again

Hope it helps to find a useful end to my problem... because if I upgrade Hikashop (and I will for sure), it wil no more work.
Could you please check this by your side and let me know ?
