Cannot click the nickname tab in IE 11
Taunusbahner reported an issue with Internet Explorer v11 where clicking on the nickname tab does not work. This issue only occurs in IE11 and not in other browsers. justin suggested checking the browser’s developer console for errors, which revealed a “Promise” undefined error.
codinghorror suspected a promises error, and eviltrout asked for the Discourse version, which Taunusbahner confirmed as the latest-release +199. eviltrout found the issue and fixed it in the latest Discourse builds with a commit. The fix was confirmed to work by Taunusbahner. Additionally, eviltrout added linting to prevent similar bugs in the future.
Good evening,
some users in my community have found some bugs with Internet Explorer v11, in the last few days.
After today i started an update, there is only one bug.
When I want to logout me from discourse, can not klick on my nickname tab.
However, this error only occours in IE11. All another browsers dooing it right.
Best regards Sven
Can you check your browser’s developer console (usually found by hitting F12 on your keyboard and clicking on the Console tab) to see if there are any errors shown in it?
Thanks for the quick reply.
Yes, there is an error.
Note: My browser has the standard German language installed.

More promises errors @eviltrout
Can you confirm which version of Discourse you are using? Because I believe this bug was already fixed.
My version installed is discourse latest-release +199.
But I have the same bug here in the discourse meta forums.
Internet Explorer Version 11.864.17763.0
Thanks for confirmation. I did indeed find some extra places where we missed the Promise object. This commit fixes them in the latest Discourse builds:

Thank you. It works now.
I’ve also added linting to prevent these bugs in the future. It will fail unless we explicitly import Promise from RSVP:
