Visual editor and text editor buttons are not visible after 3.8.1 install

I have also switched to other themes and the problem continues.

How can I restore the buttons for the visual tab and the text tab?
I have also added the “concatenated” line in the wp-config.php and the error continues.

This is how my editing options look like in WP:

I too am experiencing the loss of the editor on one of my sites. I have updated WP, turned plugins on and off and renamed the plugins folder just in case one was sneaking through, changed themes, used Google libraries plugin, turned the visual editor on and off in Users etc, etc.
I am not a newbie, but I’m stumped. I’m seeing that this is not an uncommon problem in forums. Any suggestions would be helpful.

I’m having this issue too, on a fresh install today, no plugins enabled, default theme. I can’t get to the Text view either, I click and it does nothing. Tried in Chrome and Firefox.

the same problem with me… i can`t believe how wordpress accept this crap update… are they blind ?

I have similar issue after updated my site, tried all possible suggestion above and other like disable and enable the editor show functionality – so far no results.

Interesting things that i have a plugin: Zemanta, that shows related posts only when editor is enable. And it’s working properly if I clicking on “Visual” button.

Also is started to show me en empty pages in some example

I can’t speak for anyone else, but I finally solved the problem by updating the Symple Shortcodes plugin. I needed to contact my theme developer for info on how to do it. It was not a simple matter of updating the plugin from the plugins page.
If you have this plugin, it could be the culprit. If it’s not working the visual editor is gone. If you turn it off, same thing. So it would not show up in the usual trouble-shooting.

Here is a link to instructions for my Ultra theme, to give you the idea.

o.k. i solved the problem, is was related to APC configuration to cache the wp-admin pages.

I come to this forum with this problem on only one of many wordpress sites. How do I resolve this? How do I visit the APC configuration to cache tweak?

Well
First of all I recommending you to to check for other issues that was previously listed.
FOR APC
1) make sure your APC is not caching the wp-admin files
you can check by installing the monitor tool and disable that in the configuration settings.
2)install WordPress plugin for Nginx Purge cache
3) manually clean the APC cache by restarting the PHP service you use.

Good luck.
