jQuery not define in the wordpress wp-admin


Staff member
I am using 4.1 verion of wordpress, I have tried wordpress version 3.8.1 etc, in wp-admin it is throwing jquery is not defined error. I have tried uninstalling all the plugins, deleting all the wp-admin and wp-includes files.

I have tried the following codes in wp-config,

   define('CONCATENATE_SCRIPTS', false);
   define('SCRIPT_DEBUG', true);

none of them are working, any help, Thanks
