white screen; error-warnings:

I have changed the code from ‘false’ to define( ‘WP_DEBUG’, true); Here are the warnings and errors that return in the browser.

note: I am using a tutorial where the instructor uses names such as:
function wpt_theme_styles()
and
function wpt_wpt_theme_js()
Mine are named:
function my_theme_styles()
and
function my_theme_js()

Would this even make a difference and Why ?

the following is the path that results in the browser error.
http://localhost:8888/projectWordPressThemeDev2/wp-content/themes/my_portfolio/wp-admin

Here is my function.php code

`
function my_theme_styles() {
wp_enqueue_style(‘foundation_css’, get_template_directory_uri() . ‘/css/foundation.css’);
//wp_enqueue_style(‘normalize_css’, get_template_directory_uri() . ‘/css/normalize.css’);

wp_enqueue_style(‘main_css’, get_template_directory_uri() . ‘/style.css’);
}

add_action(‘wp_enqueue_scripts’, ‘my_theme_styles’);

function my_theme_js() {
wp_enqueue_script(‘modernizr_js’, get_template_directory_uri() . ‘/js/modernizr.js’, ”, ”, false );
wp_enqueue_script(‘foundation_js’, get_template_directory_uri() . ‘/js/foundation.js’, array(‘jquery’), ”, true );
wp_enqueue_script(‘main_js’, get_template_directory_uri() . ‘/js/app.js’, array(‘jquery’, ‘foundation_js’), ”, true );
}

add_action(‘wp_enqueue_scripts’, ‘my_theme_js()’);

Thanks for the help.
