The position User6 is just a custom html module [mod_custom]
I hope you posted the content in the module ina wrong way and thats why you cannot click on it.
Replace the following code in the position user6 custom html module in module manager
<a href="http://anshell.com/rent.html" class="mostread"></a>
<div class="class-box-wrap1 class-box-style2"><div class="class-box-wrap2">
<div class="class-box"><div class="class-box-inner">
<div class="title"><h3>Rentals in NY</h3></div>
<div class="image"><img alt="Rentals in New York" src="/images/stories/demo/other/rentals.jpg"></div>
<span>Grid-based Real Estate News portal approach</span></div>
</div></div></div>
<div class="class-box-wrap1 class-box-style2"><div class="class-box-wrap2">
<div class="class-box"><div class="class-box-inner">
<div class="title"><h3>Rentals in NY</h3></div>
<div class="image"><a href="http://anshell.com/rent.html" class="mostread"><img alt="Rentals in New York" src="/images/stories/demo/other/rentals.jpg"></a></div>
<a href="http://anshell.com/rent.html" class="mostread"><span>Grid-based Real Estate News portal approach</span></a></div>
