The attribute value is incorrect.
For a color,
the value must be a name like "black" or begin with a # like "#FF00FF".
Please check the type of the attribute and depending of his type, correct the value.
Here the attribute bgcolor is a color, the value should begin with a "#"
BAD <td bgcolor="FF00FF"> GOOD <td bgcolor="#FF00FF">
