Strange topic won't display

So in my /latest I have an entry of the following:

However, if I try to read it, I only see a blank page with the title in the top bar if I make the browser size small enough and “scroll” up:

If I use the magic undocumented /raw/ URL, I get the “The page you requested doesn’t exist or is private.” message. Also note above, the value of Replies is -1.

This happens with or without customizations enabled.

Any ideas? The actual post is at:

One more thing, this topic was created by email … not sure if that makes a difference.

Anything in /logs about this? It looks like the topic was somehow invalid.

There’s also an error in the JS console if you use f12 to view it.

Nope, the only thing at all is an unrelated ActionView::Template::Error about /latest.rss.

I re-created the topic from the original email – is there any easy way to just delete the topic somehow without being able to access the wrench menu? DB?

If you have the ID, then

# ssh into server
cd /var/discourse
./launcher enter app
rails c
t = Topic.find(<id>), t.posts.first).destroy

should be enough.

Just to confirm, when you say ID, you’re saying the integer like 29123 is for this topic?

Exactly. I meant the “topic id”.

Oops, no luck:

Ok, try the nuclear option: Topic.find(<id>).destroy


That worked. Thanks. :slight_smile:

… which implies that the problem was that the topic had no first post.

Indeed, but the real mystery is why?
