Hello, I have installed Opencart 2.2 on my website and in the cart error it appears this message. I have tried with 3 opencart versions ( 2.0.0, 2.0.3.1, 2.2) and I have the same message and I don't understand what's the problem. This error appears on fresh install.

Actually i faced such similar issue while working with one of the client recently. The server sends old page back from history.
So what you see is old page. And new files are never called.

You can clear browser cache or try incognito mode in Chrome.

This error was solved finally. The error was because of server.
The server had one php module that was causing this issue.

This php module does not sent fields in $_POST when they are empty.
So in backend this issue of undefined index was coming.

When host was told about this issue explaining him that when fields are left empty, fields are not received in $_POST.
They disabled the php module and it started working fine.

Hope this helps someone.
