Stale element exception is thrown in two cases

The element is no longer attached to the DOM. The element has been deleted entirely.

When this happen you wrap your code in try catch block then you can loop and retry as many times as you need until it succeeds.

public void waitForElementPresent(final By by, int timeout){ 
  WebDriverWait wait = (WebDriverWait)new WebDriverWait(driver,timeout)
                  .ignoring(StaleElementReferenceException.class); 
  wait.until(new ExpectedCondition(){ 
    @Override 
    public Boolean apply(WebDriver webDriver) { 
      WebElement element = webDriver.findElement(by); 
      return element != null && element.isDisplayed(); 
    } 
  }); 
}
