Recently, I have experienced a rather strange problem with Stack Overflow.

I am using Mozilla FireFox as my browser.

It seems that the problem is with the stylesheet not functioning, so all the contents of the site is shown in plain text with a messed up style.I have checked the page source and the related css file exists.


More Info :

OS : Windows XP service pack 3

Browser : Mozilla Fire Fox 4.0.1

  • More info please, Browser version, OS, AddOns, proxy or (corporate) firewall? If possible test with other browsers, too. May 24, 2011 at 8:18
  • 1) Refresh the page. 2) Clear your cache. 3) Try another browser. May 24, 2011 at 9:08
  • I have disabled all plugins and extensions , removed cookies ,checked access to cdn.sstatic.net (and it's not blocked) but the problem still remains. I am behind out company firewall but that can not be the issue because it was working fine two days before and nothing has changed since then. May 24, 2011 at 9:20

    ...and nothing has changed since then. Can you guarantee that they haven't changed the rules? May 24, 2011 at 9:32

    No-repro here with FF4; this may be indeed an issue with your company's firewall and/or proxy. May 24, 2011 at 10:08

  • This seems to be a recurring error: I had the same issue half a year ago, with FF 3.6 on Windows Vista; it vanished just by itself after a day or two. May 24, 2011 at 12:40

  • I had a similar problem this morning with SharePoint SE and I posted a question on SPSE Meta (meta.sharepoint.stackexchange.com/questions/149/…) but within 4 minutes everything was working again. May 24, 2011 at 13:42

I also saw this this morning on the train coming in to work. I was browsing from my Adndroid phone with no addons, all standard Android config.
