Thank You Shai Gluskin.<br><br>I used Firebug-&gt; Console -&gt; All to check all JavaScript error.<br><div class="errorTitle focusRow subLogRow "><span class="errorMessage ">$(&quot;.menu li&quot;).css(&quot;margin-left&quot;) is undefined</span></div>

<span class=" "></span><table class=" " cellpadding="0" cellspacing="0"><tbody class=" "><tr class=" "><td class=" "><img src="chrome://firebug/content/blank.gif" title="Break On This Error" class="errorBreak a11yFocus "></td>

<td class=" "><a class="errorSource a11yFocus "><pre title="var shift = &#39;-&#39; + (Math.ceil(($(&#39;.menu li&#39;).css(&#39;margin-left&#39;).replace(&#39;px&#39;, &#39;&#39;))) + 16) + &#39;px&#39;;" class="errorSourceCode ">

...t = &#39;-&#39; + (Math.ceil(($(&#39;.menu li&#39;).css(&#39;margin-left&#39;).replace(&#39;px&#39;, &#39;&#39;))) + 16)...</pre></a><a class="objectLink objectLink-sourceLink a11yFocus "><div class=" ">dhtml_...?m04xri (line 179)</div>

</a></td></tr></tbody></table><br>From there I found that I dhtml_menu was problem. I disable module and it works.<br>Instead of using &quot;Expand on Bullet&quot;, I select &quot;Doubleclick&quot;. And now my dhtml_menu also working and I don&#39;t have Ajax problem.<br>

<div><br></div><div>If you can&#39;t do that... the next best thing is to turn play around turning off modules and finding the culprit module when the site starts working again.
