Prevent WPC_article file from being overwritten on server restart in NW 7.31 SP12

Hi,

We have modified wpc_article.xsl and wpc_article.xml . Once we upload the file to portal when we take portal server restart, the custom file gets replaced with SAP standard file.

Is there any way to prevent this issue? We are facing this issue after upgrading portal  to NW 7.31 SP12. It was working fine till SP4.

Any inputs Lorraine Fitzpatrick

Changes done :

In Portal goto Portal Content Administration > KM Content > root > etc > wpceditor > styles

select context menu for wpc_article.xsl

Edit Locally

Opens notepad

<!-- Comment out back to top Lee Lewis

     <div class="wpcbacktotop">

      <a class="wpca" href="#" onclick="javascript:window.location.reload(false)">

       <xsl:value-of disable-output-escaping="yes"

        select="wpc:getString('xsl.xmsg.back_to_top', string(/document/@locale))" />

      </a>

     </div>

     -->

Regards,
