Please provide any additional information below.
Easy fix; in function toString_attributes( ) surround:
foreach($this->attributes as $a => $v) {
  $s .= ' '.$a.(((!$this->attribute_shorttag) || ($this->attributes[$a] !== $a)) ? '="'.htmlspecialchars($this->attributes[$a], ENT_QUOTES,$
}
with:
if(is_array($this->attributes)){
  ...
}
