    Congratulation for your fantastic service! Anyway, I have just a problem: Uploading file .epub or .mobi is not allowed. Can you help me to find a solution?

    Please be sure to add that file extension to the "Extensions" settings of your upload field;

    You can put asterisk * to allow all file types.
