Nothing Happens when i Click on Add Media in WordPress Backend

Can you replicate the problem using the default Twenty Twelve theme with all plugins deactivated?

I tried with deactivating all the Plugins and reverting back to Default theme. But still the problem persists

Can we see the site using the default Twenty Twelve theme with all plugins deactivated?

Please check out the site now https://www.saudideltagroup.com/home/ I have deactivated all the plugins and set the theme to default Twenty Twelve.

Now I can see that the Add Media Button is working fine. Let me enable theme and check if it still works

When I enable the theme, the Add Media Button does not work. So this might be some theme issue. Please let me know if you have any solution for the same.

define('CONCATENATE_SCRIPTS', false );

I tried adding this above code in last second line of wp-config.php file and now the add Media button works fine.

Thank you,

Thank you, worked for me, too!

Oo, spoke too soon. When I insert the line I can’t save any more. Is this the right spot?

if ( !defined('ABSPATH') )
	define('ABSPATH', dirname(__FILE__) . '/');
require_once(ABSPATH . 'wp-settings.php');
define('CONCATENATE_SCRIPTS', false );
?>
