HI
I have a problem with IE8 whenever I try to download a file from the S2 secure are a get an error message.
I am attaching the link to the error screen shot.

On all other browsers the download works.

What can I do to fix this?

Thanks
Dan

Hi Dan.

Are you using the s2member-files folder or the Amazon S3 integration?

Could you also submit your site info just in case? s2Member® » Private Contact Form

Hi,
I am using the s2 members files folder.
I submitted the site’s info as you requested.
Thanks
Dan

Hi Dan. Sorry about the delay.

Thanks, got the email. I tried logging in to the dashboard but the credentials you submitted didn’t work. Could you please resubmit that? Please let me know again when you resubmitted it. Thanks! s2Member® » Private Contact Form

By the way, did you try all the suggestions in this guide? Knowledge Base » Common Troubleshooting Tips

By the way, here’s what Jason told me a moment ago:

We could ask him to place this in his /wp-config.php file as a quick test; and then remove it after the test is done.

[hilite pre_code]
$_SERVER['HTTP_RANGE'] = NULL;
[/hilite]

I will investigate this further tomorrow.

Could you please try that?

Hi Crisitan
What does this line of code do?
$_SERVER[‘HTTP_RANGE’] = NULL;

Dan

Thanks for the heads up on this thread :-)

$_SERVER['HTTP_RANGE'] = NULL;

This will cause PHP to ignore Byte-Range requests from a browser, and instead serve the full file regardless of what the browser asks for. The suspicion being that IE8 might be requesting a Byte-Range, but it’s requesting an invalid range. I’m going to run some tests against this theory now and see if there is anything to it.

Please stand by. This is the first report like this that we’ve had about IE8.

Theory shot down (which is good actually). I was unable to find a bug in IE8 byte-range requests.

I also ran tests at BrowserStack.com against the current release of s2Member® and IE8. So far I’ve been unable to reproduce the bug you reported here. I tested this against ZIP, PDF MP3 and MP4 files; both with and without download keys; both with and without local storage options. No bugs in these latest tests.

Can you please let me know what type of file you’re trying to download; and how large? Also, if problems persist, please post a Dashboard login so we can make an attempt to reproduce this in your environment. Thanks!

Hi Jason
Thanks for helping here.
The file is a .rar file 22.5kb in size.
I would like to say that only when copying and pasting the url in the address bar the browser causes the error.
When clicking on the link in the webpage the download is ok.
I posted a dashboard login previously, I’ll do it again.

Dan

Thanks for your reply :-)

Details received. Can you please check on the Dashboard user/pass you sent over? I can’t seem to log in. If you need to, you can submit the form again. Thanks!

Hi Jason,
I submitted the details again

Dan

Hi Jason,
Did you have a chance to take a look?

Thanks,
Dan

Hi Dan. Thank you.
~ I’m taking a look at this again now.

I was able to reproduce this on both of the following configurations.

– IE8 running on Windows XP
– IE8 running on Windows 7

The strange thing is that it only occurs ONE time (i.e. it fails initially); but if I try it again it works just fine in that browser session. I ran a quick search and found this related article at StackOverflow. See: http://stackoverflow.com/questions/3415370/ie-unable-to-download-from-unable-to-open-this-internet-site-the-request

I’m investigating this now to see if there anything we can do.

Disabling no-cache headers does seem to workaround this IE8 bug.

Please create this directory and file:
/wp-content/mu-plugins/ie8-nocache-headers.php
(NOTE: these are MUST USE plugins, see: http://codex.wordpress.org/Must_Use_Plugins)
(See also: http://www.s2member.com/kb/hacking-s2member/)

Thanks Jason,
Created the file and giving it a check.
Will update…

Dan
