I like your plugin and the fact that it has an easy to use download button. However, I'm running into a problem with this very feature!
When I click the download button and save the file to my desktop, the file is not really downloaded: it is basically empty, at 0 bytes.
Here's what I did:
I inserted the mp3 file via the Add Media button; left the title the same as the name of the file; made sure the link URL is pointing to the file, then Insert into Post. No matter what I've tried to fix this, the download file is still 0 bytes. It plays just fine, and if I save the file without this plugin activated (right-click and save as), then it saves correctly, so it's not a problem with the file.
Here is what I have done to troubleshoot:
1. disabled all plugins
2. changed themr to Twenty Eleven
3. removed plugin and reinstalled
4. removed mp3 file and re-uploaded
Next, I tried the plugin and same mp3 file on a different wordpress site (hosted elsewhere) with the same plugin settings and the same theme...and it works just fine there! So, why won't it work on the first site?! I'm not sure what could be causing this issue. Any ideas what else I can do to troubleshoot this?
I'd appreciate any help you can provide. :)
