Hi guys,

I've bumped into the same issue today.

Any zip files in the s2member-files folder are corrupt when downloaded. I've tried two different archiving apps, and Chrome & FF and the result is the same.

They can be opened with 7Zip, but not other apps, and my zips are WP plugins and cause this error when installing through the admin panel: Incompatible Archive. PCLZIP_ERR_BAD_FORMAT (-10) : Invalid archive structure

I've also tried downloading with or without an auth key, and the same result.

The same zips when shifted to another folder download, unzip and install through WP fine.

I followed through this thread which seems to describe much the same scenario: viewtopic.php?f=4&t=6410&p=14925&hilit=corrupt+download

The only difference is my zip is 7k so it's quite small.

I updated s2member with the latest update and no change.

Thanks so much for all your help guys, the plugin is brilliant and you rock!

P.S. As another point of interest, I found if I have a zip with the word "insert" in the filename download access is blocked.

Thank you for the kudos, guys!

Thanks for all those details, Kezz.

I'm emailing Jason about this.

HI

Rename your file from something like this sample.zip to sample.zip.txt and try to download it directly by copying the URL link to a new tab.

Please report back

Thanks for your help Sam.

I renamed my file to have the extension .zip.txt and downloaded via the direct URL.

The text file itself would open, but when I renamed it back to .zip extension it gave the same corrupt message.

If there's any other info I should provide, let me know.

Hi guys,

Just wanted to drop in and say, happy to pay for your time on this question if it's possible at all to hit you up for some help on this one.

Let me know if I can send you something for your trouble.

Thanks!

Hi Kezz

Sorry for the late respond.

Are you on a shared hosting account or you have your dedicated server? Is fopen enabled in your php.ini

Sam

Hi Sam,

Thanks for your help!

The site is currently on a shared host, but I do know that fopen is enabled as I use it in a plugin that works a-okay.

Greatly appreciate anything you could do to shed some light on the subject.

Cheers,

Thanks for bringing this thread to my attention.

If this is still a problem on your installation, please try this and report back.

Create this directory and file:
/wp-content/mu-plugins/s2-hacks.php

Code: Select all

<?php add_filter("ws_plugin__s2member_chunk_file_downloads", "__return_false"); ?>

* Please do NOT introduce any spaces/tabs/line breaks before or after <?php ?>.

This disables s2Member's chunked file delivery, and instead it will use a simple call to file_get_contents(). This works fine for small files, but PHP resource limitations across various platforms require us to chunk the delivery of files to prevent high memory consumption.

On some servers, chunked file delivery may also cause trouble, particularly if your server is configured to perform some form of PHP-based output compression, instead of leaving compression to Apache.

If your server is currently configured with some form of PHP-based output compression, please consider using mod_deflate for Apache instead. Perhaps something like this:

Code: Select all

# COMPRESSION FOR SPEED
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/css text/plain
AddOutputFilterByType DEFLATE text/javascript application/javascript application/x-javascript
AddOutputFilterByType DEFLATE text/xml application/xml application/xhtml+xml application/rdf+xml application/rss+xml application/atom+xml image/svg+xml
AddOutputFilterByType DEFLATE font/truetype application/x-font-ttf font/opentype application/x-font-otf
</IfModule>

Wonderful, that did the trick! Thanks so much for that!!

I just bought the pro module to say "thankyou" properly. I really appreciate your help!

Cheers,

P.S. You might find it interesting that I found a zip file of mine wouldn't download if it had the word "insert" in it. I have a plugin called "EasyOptInserter" and couldn't get the download working with any variation of the word "insert" in it.

No hassle, just thought you might like to know.

Thanks for the follow-up, and thanks for purchasing s2Member Pro.
We really appreciate your support!

Interesting. You might try this test also.
Remove the other hack that I posted, and try serving chunked files without a Content-Length header. Just remove the other hack I posted, and use this one instead. This way files are still delivered in chunks, but no Content-Length header is sent. I've seen a few servers that don't like Content-Length together with Transfer-Encoding: chunked, and this might be a good middle-ground for you.

Please report back if you can.

Create this directory and file:
/wp-content/mu-plugins/s2-hacks.php

Code: Select all

<?php add_filter("ws_plugin__s2member_chunk_file_downloads_w_content_length", "__return_false"); ?>

That worked great too and the downloads also seemed to come in noticeably faster.

Thanks very much for that!

s2Member now officially kicks the b*** of the other download protection and membership based options on the table.

I appreciate your time, especially taking the effort to give me two fixes. Awesome!

Awesome. You're very welcome.
If you get a minute, can you please let me know who your host is, and/or at least what type of server you're running exactly? I'd like to see if we can detect this problem in advance, so that other site owners don't need to find this solution in the forum. For instance, are you on a Windows server? Or what are you running exactly? A test download link would be great too, if possible. You can send private information to us through this form: http://www.s2member.com/contact/

Thanks for the kudos, Kezz!

What other download protection solutions had you tried before? Just curious.

Details received via email. Thank you VERY much Kezz!

Glad to hear that you watched Zeitgeist.

Yes, all three movies were life changers.

Hey I found out one extra piece of information for you. The server I'm on uses LiteSpeed rather than Apache.

Also, the second fix seemed to work great for almost everyone, but then 2 people contacted me still getting the same issue, so I rolled back to the first fix you gave me which got them going again.

I've asked my host for any more information they can provide about the server setup, waiting to hear back atm.

Thanks!

Thanks Kezz. I suspect this has something to do with header combinations, or possibly with output compression. Can you please email me an s2Member File Download Link so I can test for certain scenarios? I'll reply back to the email you sent, that way you can send it directly to me.

Thanks Jason, just got back to your email.

Catch you shortly!
