python selenium - Element is not currently interactable and may not be manipulated

Question

I am trying to populate form fields via selenium in python:

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

driver = webdriver.Firefox()        
driver.get("http://www.miralinks.ru/")
driver.implicitly_wait(30)
login = driver.find_element_by_css_selector('input[placeholder="Логин"]')
hov = ActionChains(driver).move_to_element(login)
hov.perform()
login.clear()
login.send_keys("login")
pwd = driver.find_element_by_css_selector('input[placeholder="Пароль"]')
pwd.clear()
pwd.send_keys("pass")

but this fails with exception:

Element is not currently interactable and may not be manipulated

Why this happens and gow to fix this?

webdriver __version__ = '2.45.0'.

Answer 1

Use a wait function before the element that gave the error.

The webdriver is trying to interact with an element not completely loaded.

Answer 2

The problem is that there are two other input elements with placeholder="Логин" and placeholder="Пароль" which are invisible. Make your CSS selectors specific to the login form:

login = driver.find_element_by_css_selector('form#loginForm input[placeholder="Логин"]')
pwd = driver.find_element_by_css_selector('form#loginForm input[placeholder="Пароль"')
