Can't upload MP3 / MP4 files
When uploading mp3 or mp4 files if you encounter the follwoing error; "Unable to open i/o files", there are a few things that you need to check to ensure that you can upload these filetypes:
- Check that you have not deleted mp3 / mp4 file extensions in DOCman's settings (Components > DOCman > Settings > Allowed file extensions). By default DOCman allows both mp3 and mp4 files to be uploaded.
- Make sure that you have sufficient disk space to store the files and that the file permissions are correctly set (CHMOD 0644)
- If you have a firewall extension installed on your Joomla site (e.g. RSFirewall), check that mp3 and/or mp4 filetype extensions are not in the banned list.
