Hi

Today I have noticed that only in IE , I can login with subdomain.domain.com but not with www.subdomain.domain.com . It means that with www in URL user can`t login into LMS .
Firefox doesn`t have this bad problem .
Can I do anything ?

I think it doesn't depend only on the browser but also (and mostly) on the server configuration.
Maybe your server is configured to support only the name without www, but Firefox is smart enough to understand what you are looking for.

Can you also check your Docebo configuration? What did you put as the server address?

server address in Docebo doesn`t affect on it . I have tried with both with www and without www , but the result was like before .
I think server doesn`t have problem because just login action doesn`t work in www mode in Internet Explorer .
