Open Inline.php file from this path /app/code/core/Mage/Core/Model/Translate/Inline.php
Now find below code in that file. (In my case line 272)
<script type="text/javascript">
new TranslateInline('translate-inline-trig', '<?php echo $ajaxUrl ?>', '<?php
echo Mage::getDesign()->getArea() ?>');
Add this code after:
if(Object.__defineGetter__)
{
var hasTranslateAttribute = function(){
return $(this).hasAttribute("translate");
};
document.observe("dom:loaded", function() {
$$('*').each(function(theElement){
theElement.__defineGetter__("translate", hasTranslateAttribute);
});
});
}
Now check it. It should work in Chrome browser now.
Enjoy :)
