    Hey Brajesh,

    A bit random but – I have a script that allows Capital Letters in Usernames. Recently it doesn’t seem to be taking effect, would you have any ideas why? Is it something you could resolve/update for BuddyDev?

    Thanks in advance,
    Graham

    	}
    
    	function remove_error( $result, $error_string ) {
    		if ( empty( $result['errors']->errors['user_name'] ) )
    			return $result;
    
    		$error_index = array_search( $error_string, $result['errors']->errors['user_name'] );

    			unset( $result['errors']->errors['user_name'][ $error_index ] );

    		}
    
    		return $result;

    Hi Graham,
    Thank you. I will test and update it.

    Thank you for sharing. We can certainly adopt it and put it on our github repos for future use.

    Regards
    Brajesh
