I also found some weird user-agent issues causing the visual and html buttons to disappear.

In chrome developer tools you can emulate different devices, also you can change browser user agents. If emulated in Iphone4 the, buttons disappear, any other user agent works well.

Try open the developer tools (right click and click inspect element), than on the developer tools panel top left corner there is a toggle devices tool, which opens a different view where you can select models. Try some (after selecting a model you have to refresh the page).

If this is some user agent problem, this will reveal it.

This chrome extension caused the problem for me, until i disabled it.
Also when I saw that there is a connection between the problem and the user agent, I reactivated and used it to set my user agent to chrome default, and now works fine.
You can try this too, its easier than the chrome developer tool.

The result “tinymce” says that for your user the tinymce editor set as default.

Well there are a couple things you can try:

– disable all the plugins
– change back the theme for any twentyxxx default theme
– add a new user with editor than administrator role
– delete the wp-includes, wp-admin directories and reupload these from a newly downloaded wp 4.3
– try login from incognito mode or from a never previously used web browser
– try shut down every antivirus program you use also programs with online web protection

My opinion is that some third party application blocks the buttons.

If not than you should put these to wp-config.php

define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, false);

These will collect error logs to wp-content directory, and wont show any errors on your site, so this is a safe mode to collect error on live websites.

Try these and post errors.

If you run in any javascript console the following:

getUserSetting(‘editor’);

Do you get tinymce as a result?

Hi, I checked everything. Php code parts, mysql, logs.
I had this issue only in chrome, there is 2 things I found:
– try to check and save, than uncheck and save Visual editor under Users/Your profile.
– I had a chrome extension (User-Agent Switcher for Chrome) which caused the removing the buttons. Try turning off the browser extension (adblock can also cause problems).

Hope that helps.
