How to use chrome extension?

I can't login?

Chrome recently changed that iframe cookies are not allowed by default. You can bypass that in a few ways

Option A

Modify lhc_web/index.php file and uncomment these lines

// @ini_set('session.cookie_samesite', 'None');
// @ini_set('session.cookie_secure', true);

Change to

@ini_set('session.cookie_samesite', 'None');
@ini_set('session.cookie_secure', true);

You might need to restart a browser

Option B

Another way is (not recommended as it will lower your browser security)

  • Enter in chrome url address chrome://flags/
  • In Search flags enter samesite
  • Change found items values from Default to Disabled
  • You might need to restart a browser


  1. Two install ways
    1. A (recommended way)
      1. Navigate to and just install extension
    2. B (advanced method)
      1. Download extension from
      2. After download open in chrome chrome://extensions/
      3. Drop downloaded file there
      4. Agree to install a extension
  2. After install should appear blue Live Helper Chat icon.
  3. Click right mouse button on icon and choose options
  4. Enter url address where live helper chat is installed without trailing slash. E.g (make sure you use your address)
    1. If LHC is installed in subdirectory path should look like
    2. if LHC is installed as subdomain just enter
  5. Click save
  6. After clicking save icon should change to P, now just click an icon and login. If you do not wish to login each time you run computer. Just check a checkbox remember me.
  7. Also to see chrome notifications you can in your application grant permision to show notifications example url in

Icons meanings

  1. F - extensions is not configure, click right mouse button and choose options
  2. P - extension is not logged to Live Helper chat, click popup and login
  3. no text - extension is logged and there are no pending chats

I can't login from the Chrome v80

A cookie associated with a cross-site resource at https:/xxxxxxxxx / was set without the `SameSite` attribute. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at and

Add this to the .htaccess file

Header always edit Set-Cookie (.*) "$1; SameSite=None; Secure"
