CSRF Error

If you're seeing a CSRF error message (a big red messy error) when logging into your Lessons.com account, don’t panic. There is a solution and you can find help below.

Why does this happen?

This error message means that your browser couldn’t create a secure cookie, or couldn’t access that cookie to authorize your login. This can be caused by ad- or script-blocking plugins, but also by the browser itself if it's not allowed to set cookies.

It can also happen when you try to access your account on a new browser tab, while you are logged into your account through an old browser tab that you maybe forgot about. Be sure to close all your browser tabs for Lessons.com, then try again. If you still get the error after closing all old Lessons.com tabs, then you can address this issue, using these steps (depending on your browser):
