This is a new install of WP 3.3.1. There are NO plugins (all have been deleted, not just deactivated). Same problem in all browsers in Mac, Linux, Windows using Safari, Chrome, Firefox, etc. Cleared cache, etc.
Here's the problem(s):
1. Clicking Screen Options does nothing. (URL shows #screen-options-wrap after) clicking
2. Widgets can't dragged, much less dropped
3. White HTML text (invisible) in Visual editor, only viewable when selected
4. Can't rename permalink page title (URL shows#post_name after click)
5. Can't upload media via multi-file upload or browser uploadI've checked the forums and haven't found a solution yet, just a lot "turn off your plug ins" and browser cache clearing, but evidently others have experienced the same. Any suggestions? Is it a javascript issue? PHP? (running PHP 5) ??? Thanks for any suggestions or solutions.
Try adding
define('CONCATENATE_SCRIPTS', false );to the bottom of your wp-config.php file (just before therequire_onceline).
define('CONCATENATE_SCRIPTS', false );
Worked for me!

这上故障让我研究了很久只有在Linux主机上才有此故障，wordpress升级到最新版4.1也是一样的有这个故障。没办法只能全部加载所有JS文件了。就在wp-config.php中用这条语句吧：
define('CONCATENATE_SCRIPTS', false );//wordpress如果主页与写文章与编辑文章与页面编辑的显示选项与帮助无法点击切换#screen-options-wrap不工作，请添加此项又折腾到1点呀！郁闷……
