HTTP Error When Uploading MP3s Ony – Pics Upload OK

Hello,

I receive an http error from the media uploader whenever I try to upload MP3 files. The status bar will say uploaded 100%, but the file will not crunch. Then I receive the message in red ‘http error’.

This only happens with mp3s. Since receiving this error I have successfully uploaded very large picture files and everything functions normally. I have uploaded 2 mp3 files that were larger in MB than the one I am currently trying to upload and they loaded fine.

I have a brand new install of WordPress 3.6. I am using the twenty thirteen theme.

The plugins I have installed are AntiSpam, Favicon Rotator, Shareaholic, Slideshow, and W3 Total Cache. I have disabled all of these and I still can’t get the uploader to work for mp3s.

I have gone under Settings/Media and unchecked the organize my uploads into month and year based folders. I was still unable to upload mp3s.

I added a bit of code to a htaccess file I created in wpadmin. I can’t remember what it was. I deleted it as that didn’t work. I emptied my cache. I changed the content and upload folder permissions to 775 and 777 respectively. That did not work either. I have also tried switching browsers and using the browser upload. Neither of those worked.

Any help is greatly appreciated.
