Hidden "Ask a Question" button on forums

I went to post on these forums and found that there was no button to as a question or start a discussion, but I could still reply to existing discussions. I check the page and found that the buttons had been given a “display:none” style. I tried in Safari in case this was a misbehaving Google Chrome extension but had exactly the same.
Using the developer tools in Google Chrome I was able to make the button appear to be able to post this.

Very weird, I’m seeing the same thing. Although, as I’m viewing a thread like right now, the Ask a Question button is visible at the upper right. But not when viewing the list of threads in a forum.

I’ve reported the issue.

Same issue here, it only shows up on some specific threads but not others.

I can see it on this page but not other pages where I want to post.

Seems to be fixed. Thanks, Otto.
