Remove straight quotes from content and code

Hello
I’m trying to write a simple wordpress theme.
I’m seeing to be enclosing content in straight quotes on it’s own and I’d like it not to do that.
I’ve looked around a bit here and online and added the following lines to my functions.php file:

remove_filter(‘the_content’, ‘wptexturize’);
remove_filter(‘the_content’, ‘wpautop’);

it still seems to continue to enclose the post content there, though

I’ve also tried to write an extremely simple plugin:

/*
Plugin Name: portfolioShow
Description: shows portfolio
Version: 1.0
Author: Keith Bonarrigo
Author URI: http://example.com/
*/
function get_port(){
return “it worked!”;
}
add_shortcode(‘port’, ‘get_port’);

The plugin is activated but it has the same effect.
You can see this text close to the top of the page here:
http://s121744933.onlinehome.us/wordpressAngular/

and when I type [port] it renders those very characters in quotes, rather than the correct text.

I’m (obviously) new to this and I’d really appreciate some help here

thanks very much
