Problem with the text editor of WordPress

After one of the WordPress updates I started to have an issue with the text editor. Basically none of the features worked, and after saving a post in plain text the data was deleted.

I found a solution on this post: edit the file “wp-config.php” and add a line of code.

//previous line
if(!defined(‘ABSPATH’))
define(‘ABSPATH’,dirname(__FILE__).‘/’);
//Add this line
define(‘CONCATENATE_SCRIPTS’,false);
It worked, so I save this solution just for my poor memory.
