W3C Error

Hello,

i got a W3C Error with the attachment field:

Error: Attribute value not allowed on element input at this point.

When i changed the line 1413 in the /includes/class-fscf-display.php and remove the “value” there it is solved but is there an other way to remove the “value” for the input type=”file”?

Best regards,
Harry
