Weird bug with forum display

[Togath]

A few minutes ago i came to the forum and found it displaying like this;

but only the forum segment of this website does this, and there are no little pop-up ads, and my virus scan didn't detect anything.
Any idea what's going on?
edit: it apears to have gone back to normal for the moment, but does anyone know what caused the error?

Most of the forum styling seems to be malfunctioning, by which I mean "absent". E.g., links use default colors, background is mostly glaring pure white, posts and post lists are undifferentiated, script-powered functions (like the post editor) don't work, and so on.

Firefox is giving me this error in the console:

Error: SyntaxError: invalid XML attribute value
Source file: http://www.giantitp.com/forums/clientscript/vbulletin_global.js?v=3611
Line: 9, Column: 14
Source code:
<LINK REL=stylesheet HREF="/Style/style.redesign.css" TYPE="text/css">

There are also some other errors that I think are caused by that:

Error: ReferenceError: vBulletin is not defined

Refreshing cache doesn't help.

Edit: Bam, it's gone now. Phew. (Another poster noticed the same thing at the same time.)

I had that bug a few minutes ago, but hadn't known what caused it.
on the plus side, from the sounds of it it wasn't my computer that malfunctioned

The page loaded incorrectly, missing the file that has the forum layout information.
Just refresh the page and it almost always displays correctly.

Just refresh the page and it almost always displays correctly.

I get this error if the internet connection at my end is really slow. I always figured that the browser detects the slow connection and displays a simple HTML version of the page.

Rawhide will need to be the one to give any sort of answer, but I'm merging the two threads on this subject to make it easier for him.

It's what happens when a page starts loading - the core text loads first, followed by the images and then the style sheet. On a slow connection, I'm guessing the page starts loading and then gets hit with a time out before it can finish loading. As Yora said, a refresh fixes the issue. :smallsmile:

This happens from time to time, I've observed the issue happening very infrequently since at least last year. It happens when your computer does not load the CSS file.

It's extremely rare and if you wait a minute then refresh, it should go away.

doesnt it have something to do with the javascript settings on your computer? i sometimes get that issue as well but it always sorts itself out.
