アイコンが表示されないのは、svg-sprite ファイルが読み込まれていないためです

I just received attention that Discourse have had a new version. So I update my Discourse to 2.2.0.beta5 and now find that almost all icons have missed. Do you met the same problem?
By the way, I’m using a custom port instead of port 80.

I think this information will be useful, who knows why it can be so. Your forum does not load the file:

P.S. IMHO, it is better to edit the first message, so as not to create multiple consecutive answers.

So the file not loaded is what?

Custom ports are not supported. You need to be on 443 or 80.

OK, thank you. Cause I’m from China and port 80 is banned, I can’t use port 80. But I will try port 443.
