"GitLab may not work properly because you are using an outdated web browser."

Any ideas why I would get this error even though I have Internet Explorer 11?

“GitLab may not work properly because you are using an outdated web browser.”

Just want to bump it up since I am still having the issue. I’d like to solve it before rolling out GitLab to our entire dev team. Thanks.

This MR should have fixed that. And here is the bug report https://gitlab.com/gitlab-org/gitlab-ce/issues/2271

I pinged Stan to investigate more.

Actually, what GitLab version are you running? This should be fixed with latest stable.

GitLab 8.0 works without those warning messages using IE11, with or without compatibility mode. I just tested this again on GitLab.com. What version are you using?
