Yesterday I was logged in to DPChallenge as usual using Firefox as my browser. Whilst navigating beteen two threads the display of the site changed - the menu bar has dropped by about half an inch, ribbon icons have gone from profile pages, the triangles that display thumbnails have gone, watched threads have gone, and so have the boxes to post to threads. I have cleared out the cache and deleted all DPChallenge cookies. I've logged out, ogged in, re-booted, but nadda, nothing, zilch.
Internet Explorer works fine, but I do prefer to work in Firefox. Anyone have any ideas how to get the site to display as it should?
Are you running Greasemonkey with any user scripts? If so, disable that bad boy and see if the problem goes away. If it does, disable the scripts one at a time to see who the culprit is. I got nothin' if you're not using Greasemonkey.
Actually, now that I think about it, it sounds more like AdBlock has gone crazy and is blocking a bunch of useful images. Turn that guy off too and see what happens.
