Most probably you are going to run into this problem if you are running an older WordPress page with lots of plugins or themes installed (which isn't optimal). This problem can have different causes, i am going to explain the cause which fixed it for me. Others are complaining about plugins creating this error. For me it wasn't any plugin creating this error. We got no information from the console, why the visual editor is hidden.

Disable all plugins

Firstly i've tried to disable all plugins. Sometimes it happens that other plugins are interfering with the ACF or visual editor plugin. To make sure that this wasn't the cause, disable all plugins. Now you can hard-reload your browser (CTRL + F5) and try if the editor is showing up. For me this wasn't the fix, but it could be.

Solution

For me the solution was to add a simple line to the wp-config.php file which tells the wordpress either to load the scripts seperatly or concatenate them into one url. I've set this constant before the DB declaration to false. After that I've hard-reloaded the page with CTRL + F5 and the visual editor was back. You can copy the line below and paste it before the DB_NAME constant:

define('CONCATENATE_SCRIPTS', false);
