Page loads blank until refresh

[thekook]

Hey there my forum is running on /forum thanks to nginx, but I have this behavior where when I follow any NodeBB link (e.g. click on a category) the page first loads blank, but appears perfectly if I refresh/reload. The page isn't totally blank initially, but I see the loading circle graphic.

The only things I see in inspector is the socket.io polling and an error that doesn't exist if I refresh.

Console error:

ajaxify.js:84 Uncaught TypeError: Cannot read property 'name' of undefined
    at ajaxify.js:84
    at Object.success (ajaxify.js:407)
    at c (jquery.js:3500)
    at Object.fireWith [as resolveWith] (jquery.js:3630)
    at E (jquery.js:9796)
    at XMLHttpRequest.<anonymous> (jquery.js:10057)

Thanks!

What is your url in config.json? Does it have /forum?

Hmm it doesn't!

{
    "url": "http://localhost:4567",
    "secret": "secret",
    "database": "redis",
    "port": "4567",
    "redis": {
        "host": "127.0.0.1",
        "port": "6379",
        "password": "",
        "database": "0"
    }
}

Changing it to where it actually loads:
"url": "http://localhost/forum",
or
"url": "http://localhost:4567/forum",

Causes this error when I refresh the forum.

Seems like it breaks when I remove :4567 from the URL. Otherwise it's happy.

Cracked it! I had all this nonsense in my nginx from googling around. here is what worked.
