Check your 'singles.htm' or other HTML pages in which you use tooltips. and check for the following code
Code:
<span id="WzClOsE" style="background: rgb(153, 0, 0) none repeat scroll 0% 0%; position: relative; left: 2px; padding: 5px; cursor: pointer; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; color: rgb(255, 255, 255); font-family: verdana; font-size: 12px; font-weight: bold;" onmouseover="tt_OnCloseBtnOver(1)" onmouseout="tt_OnCloseBtnOver(0)" onclick="tt_HideInit()">Close</span>
And comment that code completely. Later if you want you can remove that. First do it in one page and check if it is working then do the same thing in other pages too.
