I have some issues with the Text editor not showing up after I have updated and moved a laytheme website.
I already tried deactivating all third party plugins.
Also I tried editing the wp-config.php like described here:
Make sure in "User" → [Your User] → "Disable the visual editor when writing" is not checked.
Also make sure you add "define('CONCATENATE_SCRIPTS', false );" to your wp-config.php.
Any Ideas what could be wrong?
