Question

When I run below Program, Code "option2[opt2].click()" work well.
But second "option2[opt2].click()" occur "StaleElementReferenceException"
I tried to solve this problem with "time.sleep(), implicitly_wait(), WebDriverWait(browser, 30).until(EC.presence_of_element_located((By.XPATH, {Xpath}).
But Doesn't work.
What is the problem........
#If you run my program, you can understand my code easily. I am Beginer in Programming and Korean. If explanation is not enough... sorry :( Please help me........
