html - Bad value ... for attribute rel on element a: The string ... is not a registered keyword -

I am trying to debug my website, but I do not know how to get rid of these errors.

Relative A: String Lightbox [322] is not a registered keyword on the property for the Bad Value Lightbox [322] element. I think everything is very same about these 45 errors.

HTML

  & lt; Div class = "large-3 column" & gt; & Lt; A href = "http://timberlife.nl/wp-content/uploads/2014/09/BUITENHUIS-1.11.jpg" rel = "lightbox [318]" title = "i 40 m2 with boot" class = "cboxElement" data - Target = "Flare" & gt; & Lt; Img class = "aligncenter wp-image-705-size-medium" src = "http://timberlife.nl/wp-content/uploads/2014/09/BUITENHUIS-1.1-2-200x300.jpg" alt = "Butinehus 1.1 "Width =" 200 "height =" 300 "> gt; & Lt; Br>  

I am using a plugin to use the lightbox on my images. I am having a problem where u has a plugin for a scroll effect Is using.

Bad values ​​for element m_PageScroll2id attribute on a rel: string m_pagescroll2id is not a registered keyword.

Many thanks
