I get this error when uploading an MP3 file to topics and replies:
Fatal error: Call to undefined function wp_read_audio_metadata() in /home2/dlenef/public_html/db/wp-admin/includes/image.php on line 125
Uploading a JPG does not cause the error.
After the error and viewing the post, the file attachment is actually completed and present. However, there's another problem...
Attempting to upload multiple files causes the same error, but only one file attachment is displayed in the post.
