hey Hassan,
I am sorry for the delay of this reply,
I have checked in your this post ->
http://loopec.com/index.php/makaleler/hasan-post , it seems like you have copy entire one of the page source in `code` block, inside the source content have included `HTML` and `JavaScript` language, that will messed up if you only set to use language "HTML" type in `code` block. (Check my screenshot below.)
This following script code should be put in other `code` block and set to use language `JavaScript` type.
<!-- Mainly scripts -->
<script src="<c:url value="/resources/js/jquery-2.1.1.js" ></script>"></script>
<script src="<c:url value="/resources/js/bootstrap.min.js" ></script>"></script>
<script src="<c:url value="/resources/js/plugins/metisMenu/jquery.metisMenu.js" ></script>"></script>
<script src="<c:url value="/resources/js/plugins/slimscroll/jquery.slimscroll.min.js" ></script>"></script>
<!-- Custom and plugin javascript -->
<script src="<c:url value="/resources/js/inspinia.js" ></script>"></script>
<script src="<c:url value="/resources/js/plugins/pace/pace.min.js" ></script>"></script>
Example : this is my test post ->

Hope this will helps.
