Zip files corrupt when downloaded

[Allcow Jim]

I have created a zip file which opens fine.

I download it to eStore (v6.8.9) and generate a link through the admin functions. The file will not open and I get the message:

“cannot open file <>. It does not appear to be a valid archive.

If you downloaded this file, try downloading the file again.”

I have done this. It makes no difference.

I have searched through the forums and tried changing the download method to 2, 4 and 6 as suggested in a previous post. This makes no difference.

I then downloaded the zip file to the Amazon AWS S3 storage system. I can then open the file fine.

Why is this? Is there any other method I can use which will enable me to store the file on my own site? The file is 890kB.

Please check the following checklist to make sure you are not doing any of those:

Are you using a caching plugin? If yes then which one? From your explanation, it looks like a gzip compression type issue which usually can happen from a caching plugin’s gzip compression setup.

I have been through every item on the checklist and it does not work.

I do not have a caching plugin on this site.

There are no .htaccess or .htpasswd files in the downloads directory of the plugin.

HOWEVER

If I cut and paste the Digital Product URL into the browser it downloads and unzips fine (so has uploaded to the site ok?)

If I cut and paste the Admins Setting Generated download link into the browser, it does not download or unzip and gives the error message outlined above.

Could you please post one of the links that **DOES NOT** work?

[admin]

I will take a look at your site. Please reply to the email that I sent you.

[Allcow Jim]

I was just completing the form you sent and thought I would try one more time. This time I unchecked the Downloadable box below Digital Product URL and the process worked OK!

Please can you explain the security implications of this. Should I just accept this process or would it be better to investigate why it doesn’t work fully encrypted?

Your help and advice is much appreciated.

Please fill in the details so I can do a final check myself too.
