Visual/Text not working correctly in backend

Hi,

On one of my sites just being made live today the All-In-One-SEO plug in stops the editor visual/text from working correctly. The editor window opens and shows OK but will not enable you to switch between the visual editor and text editor.

When turned off it works fine.

I have found a solution in editing the wp-config.php file by adding this code:
define( ‘CONCATENATE_SCRIPTS’, false );

Other installed plug ins include:
