Brou ya incluí la librería WriteHTML pero no funciona me tiro este error.

Unknown component type 'reportProduct'. This may be caused by the following parsing error in the reportProduct class file: [Notice] Constant FPDF_VERSION already defined (@line 10 in file C:\xampp\htdocs\sacc\protected\modules\fpdf.php).
