title: Can't click on a login button using selenium
body: <p>I try to login to this page through selenium.</p>
  
  <pre><code>https://cloud.fitbulut.com/kullanici/giris
  </code></pre>
  
  <p>I can enter my password and username via selenium but cannot make it to login by clicking on the button named 'Giris'.</p>
  
  <p>I have tried this one but it gives <code>NoSuchElementException</code> error.</p>
  
  <pre><code>driver.find_element_by_class("btn btn-primary btn-aut").click()
  </code></pre>
