All of a sudden, the audio to my slideshow is no longer working. I tried to upload a new file, but that doesn't work either. I notice that the size of the file only indicates KB. Before, I believe that it actually showed the size of the file.
I am using Photocart 6.1.3.
It is probably too large and not uploading properly. So after you try to upload it, you will need to FTP to your site and navigate to the Photo Cart -> slideshow_audio folder then also upload it there.
