Download doesn't work: 0kb .mp3

I’ve commented that line out now, and the update is definitely live. But makes no difference.

I just recorded an MP3 and uploaded it just to make sure it wasn’t something strange with the files, but still the same issue.

I think your problem is on your Server configuration somehow… It’s working fine on all the installation I have on several web servers.

I just set a test page with three instances of the miniAudioPlayer
https://pupunzi.open-lab.com/audio-test/

1. the first points to one of your audio file
2. the second points to an audio from the media files
3. the third points to an external audio file (the same as 1)

The only one that doesn’t download is the one pointing to your server…
Hope this can give you some hint to solve the problem (that is not to the plugin side).

Hi Matteo, thanks for your help. My website is hosted with a major UK host, I’ve contacted them and they have said:

“That code is attempting a loop-back connection, which are prohibited on our systems. A loop-back connection is where a script opens a connection to the internet, only for that to loop-back to the same server where the script itself is running from. This is inefficient and can cause problems on our systems – instead, any scripts should access or execute any local files or scripts through the local file system, and not through the internet.”

Is there anything that can be done to use securely use the local path?

What do they mean?
do they want a relative path instead of the absolute URL?

Anyway that sounds really bizarre… all the other servers accept a loop-back connection… If what they are saying is true it should have worked from the test page I published as it is not on the same server as your… But it doesn’t.

Sorry but I can’t make any changes in that way as this is not the common behavior on the server side.

What I could suggest you is trying placing the audio files on any other server (like drop box for example) and point to them instead of using the media uploader of your WordPress installation.

Bye,
Matteo

From what I’ve seen, related problems occur with some WordPress backup plugins which interact with files.

Here’s some text I found on another host’s website:
“If your script attempts to make an HTTP connection to a URL on the same server then that will fail. This is because loopback connections like that are blocked on our servers because they can be exploited by attackers. Best practice would be to not use a loopback connection to access a file on the same domain, and instead use a local include.”

My host was suggesting accessing the files via a path such as /home/the-sites/thewebsite.com/public_html/

Matteo, couldn’t you insert something like the following around line 10 of map_download.php – could this, or variation of it work for everyone?

$web_root = $_SERVER["DOCUMENT_ROOT"];
$web_address = $_SERVER['HTTP_HOST'];

$file_url = str_replace ('https://'.$web_address.'/','',$file_url);
$file_url = $web_root . $file_url;

I’m sure it could be tidied up!

It would perhaps work for audio file on the same domain but not for audio from different domains…
Anyway, does it work for you?

Yes, Matteo, it works for me thanks. I’m just a bit worried about the plugin being upgraded and the downloads stop working without anyone noticing ??

I’ll make the fix for that in the next update; just need to make some test to prevent some breaks in other situations.

Thanks a lot Matteo, that would be fantastic!

I have a problems with download MP3.

Work for registered users.

Not work for unregistered also i make unregistered the hability to download. give me a 403! and this cannot be fine because user can download mp4 without problems with the same permissions and another plugin

Was there ever an actual fix for this? I am experiencing a similar issue, file is hosted at libsyn and plays fine but when I click the download button from the player, it downloads an “mp3″ that is 0k. If i use the class=”map_excluded” on a text link it downloads fine, just not through the icon on the player. Any Clue?

Have you tried every single bit of advice in this post?

If you have followed every bit of advice and spent some good time troubleshooting, then I would start a new thread because your problem might be different to mine.

Make sure you check your error logs too.

I’m not sure if there was a fix in the main code because I added my own fix which you can see above, but your problem might be different.
