As a temporary solution you can change the following code:

<!--
<script language="javascript" type="text/javascript" src="{/root/urls/js}util.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxError.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxXmlRequest.js"></script>
<script language="javascript" see more type="text/javascript" src="{/root/urls/js}BxXslTransform.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxForum.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxEditor.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxHistory.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxLogin.js"></script>
<xsl:if test="1 = /root/logininfo/admin">
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxAdmin.js"></script>
</xsl:if>
-->

<script language="javascript" type="text/javascript" src="{/root/urls/js}loader.php"></script>

to


<script language="javascript" type="text/javascript" src="{/root/urls/js}util.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxError.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxXmlRequest.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxXslTransform.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxForum.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxEditor.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxHistory.js"></script>
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxLogin.js"></script>
<xsl:if test="1 = /root/logininfo/admin">
<script language="javascript" type="text/javascript" src="{/root/urls/js}BxAdmin.js"></script>
</xsl:if>

<!--
<script language="javascript" type="text/javascript" src="{/root/urls/js}loader.php"></script> -->

in orca/layout/base/xsl/canvas_includes.xsl and recompile languages and clean browser cache.
