Opera Webdriver not working
First thing you should know about Selenium is even if you are not having a element you are trying to click or any other kind of error, there would not be any error thrown by the driver in Java.
Apart from that I want to know whether you are not able to click a particular element or is it not working for any element on that page?
Secondly, I would like to know whether how are you getting that element, by id, css, xpath or something else?
I know this is not the answer to this question. I don't have 50 reputation, so I had to do this here instead of putting it as a comment!! Please ignore.
