Discussion board in Sharepoint 2013 throws :Save Conflict. Your changes conflict with those made concurrently by another user
<p>I am trying to create a discussion item in SharePoint 2013 discussion board and I got following:</p>

<blockquote>
  <p>error "Save Conflict. Your changes conflict with those made
  concurrently by another user. If you want your changes to be applied,
  click Back in your Web browser, refresh the page, and resubmit your
  changes". When i try to modified the column and try to update the item
  i.e  <code>spItem.UpdateOverwriteVersion();</code> I got the error.</p>
</blockquote>

<p>I found that the SharePoint 2013 discussion board has Receiver class </p>

<pre><code>&lt;UpgradeActions ReceiverClass="Microsoft.SharePoint.SPDiscussionsListUpgradeFeatureReceiver"
                ReceiverAssembly="Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"&gt;
  &lt;VersionRange EndVersion="15.0.1.0"&gt;
    &lt;CustomUpgradeAction Name="EnsureFeaturedDiscussions"/&gt;
    &lt;ApplyElementManifests&gt;
      &lt;ElementManifest Location="CustomActions\Ribbon.xml"/&gt;
    &lt;/ApplyElementManifests&gt;
  &lt;/VersionRange&gt;
  &lt;VersionRange EndVersion="15.0.2.0"&gt;
    &lt;CustomUpgradeAction Name="EnsureDisableGridEditing"/&gt;
  &lt;/VersionRange&gt;
  &lt;VersionRange EndVersion="15.0.5.0"&gt;
    &lt;ApplyElementManifests&gt;
      &lt;ElementManifest Location="ListTemplates\Discussions.xml"/&gt;
    &lt;/ApplyElementManifests&gt;
  &lt;/VersionRange&gt;
  &lt;VersionRange EndVersion="15.0.6.0" BeginVersion="15.0.0.0"&gt;
    &lt;CustomUpgradeAction Name="SetPagingRowLimitForViews"/&gt;
  &lt;/VersionRange&gt;
  &lt;VersionRange EndVersion="15.0.7.0"&gt;
    &lt;CustomUpgradeAction Name="FixupViewJSLink"/&gt;
  &lt;/VersionRange&gt;
&lt;/UpgradeActions&gt;
</code></pre>

<p>Does it can effect in this problem.</p>
