I have taken over a website and it seems the plugin and core updates have been hidden.

I have checked the wp-config:

define( 'WP_AUTO_UPDATE_CORE', false );

and functions.php (for anything along these lines)

add_action('after_setup_theme','remove_core_updates');
function remove_core_updates()
{...

and checked there are no plugins which would do this.

I also did a manual update but it broke the website.

Is there anything I've missed?

**edit

ok so i tried a manual install on live and got an error in the wp-includes/load.php i had to do a restore from the host but it still means i am unable to update.

Thanks
