xpath click fails in Chrome

Question

I tried using xpaths obtained from xPathsOnClick Chrome extension. Neither worked in Chrome

/html/body/div[@id='content']/section[@id='landing']/button[@class='wide'] 
//section[@id='landing']/button[@class='wide'] 

System.out.println("clicking xpath");
driver.findElement(By.xpath("//section[@id='landing']/button[@class='wide']")).click();
Thread.sleep(2000);
System.out.println("clicking xpath again");    
driver.findElement(By.xpath("//section[@id='landing']/button[@class='wide']")).click();
Thread.sleep(2000);    

I then tried to generate a script by recording clicks in FireFox using Selenium IDE, which recorded this click. This works when I run the selenium script using the FireFox Driver in my JUNIT4 test, but fails when I use ChromeDriver:

driver.findElement(By.cssSelector("button.wide")).click();

But I need to run my test in Chrome. What could be causing my script to fail in Chrome but not in FireFox?

Here is my stack trace that is returned when this errors.

I put a Thread.sleep(5000) immediately in front of the click method but it still errors with the same message

Thread.sleep(5000);          
driver.findElement(By.xpath("//section[@id='landing']/button[@class='wide']")).click();
Thread.sleep(2000);

Answer 1

The problem was the elements were behind an iFrame. Its not necessary for me to test it through the iFrame so I was able to resolve my issue.
