I’m having the same issue but there’s no screen options link. I checked my other WordPress blogs and the screen options link appears in all of them, as well as everything else.
I disabled all the plugins on my blog and the issue still exist. I went to my profile and checked the box “Disable the visual editor when writing,” then clicked “Update Profile.” Next, I unchecked the same box and clicked “Update Profile” again. The issue still exist so now I don’t know what else to do. I also, updated WordPress 3.1 again and that didn’t correct it either.
I have been using the Mozilla Firefox browser and recently installed the new update — the issue still exist. I tried the Safari browser and behold the post excerpts or custom fields and Screen Options link are visible.
So there seems to be a conflict between that one WordPress blog and Mozilla Firefox. I am completely baffled by this!
Once final note, any link I click such as Post, Appearance, Tools, Settings or whatever, I get this odd appearance as if the form isn’t going to display completely but then it does. This may be all related to the issue.
Any ideas on how to correct this will be greatly appreciated. In the meantime, I’ll continue my research.
