WordPress MU

I've installed and set up WordPress MU and today I started to dump in content. The visual editor is not properly working. It only shows the media upload button but does not have any other formatting items from the WYSIWYG. The text does not appear unless highlighted either...

Here are a couple screen shots. I've done some Googling but can't seem to find any solutions. Should I reinstall? How do I solve this?

Check your user profile settings. You can turn off the visual editor for a profile.

It is turned on. As you can see in the screen shots, the visual tab is showing. It just does not have any of the formatting options.

Then a plugin is interfering. Turn 'em all off, then back on one by one, checking each time.

I'm having the same problem on a _fresh_ install of WPmu 2.8.4a. Visual Editor is turned on in user profile, no plugins installed. visual tab is showing but theres no editor-toolbar and text is showing with html-tags.

- check it in different browsers
- make sure you uploaded all the files

All files uploaded, neither Opera 9 nor Firefox 3 nor Internet Explorer 7 work. Issue reproduced with new WPmu-Install on another Server.

You don't have some javascript blocking plugins on the browsers, do you? Unlikely considering the variety that you've tested but I'm just confused by what it could be.

2.8 updated the TinyMCE editor to 3.2.4.1. It's a third party opensource component, not something written specifically for WordPress. Maybe check the TinyMCE project site to see if it's TinyMCE or WordPress that is actually causing the problem? Does this editor load?

No JavaScript-blockers on the browsers and the TinyMCE on the project site loads just fine :-)

Administrating a blog on wordpress.com, the dom of the edit article page looks like this

div id="postdivrich"
  div id="editor-toolbar"
    ...
  div id="quicktags"
    div id="ed_toolbar"
  div id="editorcontainer"
    textarea id="content"
    span id="content_parent"
  table id="post-status-info"

where elements with ids "quicktags" and "content" are switched between css display:none and display:block and represent the HTML editor whilst span-element with id "content_parent" is switched between css display:block and display:none and represents the visual editor/tinymce.

On my fresh install of WPmu 2.8.4a, the span-element with id "content_parent" is missing and switching from HTML to visual editor the "quicktags"-element is hidden by setting display:none while the "content"-textarea stays visible.

hope this helps to identify the problem.

I haven't been able to replicate the issue and I have several 2.8.4a installs going....

Has anyone else found a solution for this problem? I've disabled all of my plugins and can't see any change.

Dito here. Have the exact same problems, and have tried all solutions proposed above, but with no result.

Wordpress.com seem to have had the same problems a month ago. From what I've heard, that was resolved.

Running 2.8.4a

I'm using 2.8.6 and getting this problem on one of my websites. It is not happening on all of my websites which are also using 2.8.6..strange. Could it be a server side problem?

If anyone locates the problem, please drop feedback. Thanks.

Nothing helped to me - BUT, then I found in IE 8 bug console the problem. I had to enable GZIP compression output on my server.

found something that helped me....make sure the wp-tinymce.php file is executable inside wp-includes/js/tinymce

it wasnt by default for me on fresh install and bout drove me nuts until i discovered it searching the hard way.....

I have same problem on my Wordpress MU 2.9.2.

I try almost everything:
- copy fresh copy of wp-admin adm wp-includes directory,
- clear browser cache,
- add define('WP_MEMORY_LIMIT', '64M'); line in wp-config.php
- add define('CONCATENATE_SCRIPTS', false); line in wp-config.php
- try all browsers and operation systems.

Only thing what help is restart Apache service on my VPS. But this works only for couple of hours. This bug repeats time after time. I am so upset... Should I downgrade to 2.7.1? :(

turn off ALL your plugins, including those in mu-plugins. revert to the default theme. Now try it.

The problem should be elsewhere as I can see the editor when I enter any of the blogs' back-ends but some of the blog owners can not! The editor remains hidden for them. Any other suggestions?

uf, I'm sorry, the users had switched off the editor themselves. So, no problems with the editor here!
