I noticed a typo in the file mdb-file-upload.js There's a triple }}} instead of a double }} in lines 56, 57 and 58

    fileSize: 'The file size is too big ({{ value }} max).',
    minWidth: 'The image width is too small ({{ value }}}px min).',
    maxWidth: 'The image width is too big ({{ value }}}px max).',
    minHeight: 'The image height is too small ({{ value }}}px min).',
    maxHeight: 'The image height is too big ({{ value }}px max).',
    imageFormat: 'The image format is not allowed ({{ value }} only).',
    fileExtension: 'The file is not allowed ({{ value }} only).'
