Responsive template, no additional plugins, possibly a day or two old installation, but didn't find comment on the issue in this thread.

meta name for author in the header is not ended properly:
Code:
<meta name="author" content="">
I removed the content between the quotes, but that is properly populated, the issue is that it doesn't resolve to:

Code:
<meta name="author" content="" />
Sorry for stopping there on the research with only reporting the issue and not a fix. No other template(s) installed, no modifications loaded (other than was testing the init_canonical modifications suggested on another thread and started looking at the source code to find this issue).

Also, two "errors" reported in validation, though have also seen "on the internet" that it may not really be an issue...

required attribute "type" not specified for both areas.
Code:
<script> if (typeof zcJS == "undefined" || !zcJS) {   window.zcJS = { name: 'zcJS', version: '0.1.0.0' }; };  zcJS.ajax = function (options) {   options.url = options.url.replace("&amp;", "&");   var deferred = $.Deferred(function (d) {       var securityToken = 'obscured to not publicly post an SID';       var defaults = {           cache: false,           type: 'POST',           traditional: true,           dataType: 'json',           timeout: 5000,           data: $.extend(true,{             securityToken: securityToken         }, options.data)       },       settings = $.extend(true, {}, defaults, options);
Where the initial <script> does not have a type assigned to it.

Same issue at bannerSix for the following "advertisement?" which would be a database population issue I believe not so much a "code" issue.

Code:
<!--bof- banner #6 display --> <div id="bannerSix" class="banners"><script><!--//<![CDATA[    var loc = '//pan.zen-cart.com/display/group/1/';    var rd = Math.floor(Math.random()*99999999999);    document.write ("<scr"+"ipt src='"+loc);    document.write ('?rd=' + rd);    document.write ("'></scr"+"ipt>"); //]]>--></script></div> <!--eof- banner #6 display -->
