Hi,
I’m newbie in wordpress .
In my wp with theme 1915 i have installed plug-in and have pasted code on widget text. Now audio appear but don’t know how to play a mp3 with player. Have uploaded mp3 in http://www.andrelephunk.com/audio folder but cant play it. Always message “file not found”
Look for it on http://www.andrelephunk.com/

I like a default mp3 .
