Theme errors because of functions.php


I'm in How to Build a WordPress Theme following all the process but with my own webpage and my own HTML code, etc. Everything is working just fine, except that I started noticing some errors in the Admin Panel. For example, when I want to update a page adding new content (or a blog post), it redirects to wp-admin/post.php but the page is blank, and my page/post is not updated (it happens with every page/post).

I changed the theme to the default (Twenty Twelve) and all worked perfectly fine, so I realize it was related with the theme I was creating, not WP. I started erasing files to find out which had the error. When I erased functions.php, the pages/posts updated fine, so it is this file.

So, I erased parts of the content, and finally all the content to find out where was the error, but even when I erased all the content, I couldn't still update the pages/posts. It only works when I erase completely the functions.php file.

Although it only works with all the file erased, I'll copy the content of the file:


// Load the Theme CSS
function theme_styles() {
    wp_enqueue_style('normalize', get_template_directory_uri() . '/css/normalize.css');
    wp_enqueue_style('grid', get_template_directory_uri() . '/css/grid.css');
    wp_enqueue_style('googlefonts', 'http://fonts.googleapis.com/css?family=Amatic+SC');
    wp_enqueue_style('main', get_template_directory_uri() . '/style.css');
    wp_enqueue_style('fonts', get_template_directory_uri() . '/css/fonts/fonts.css');

// Load the Theme JS
function theme_js() {
        wp_enqueue_script('theme_js', get_template_directory_uri() . 'js/theme.js', array('jquery'), '', true);

add_action('wp_enqueue_scripts', 'theme_js');
add_action('wp_enqueue_scripts', 'theme_styles');

// Enable custom menus


Can someone help me, please?

Do you have any extra returns after your closing php tag? I always leave that final closing php tag off on the functions.php file so I do not have to worry about that. That could be your issue.

Is this a custom theme or a child theme?

Leading / on js/theme.js is missing.

You're right, thanks!

But still it isn't working...

Have you gone through, deleting one row of enqueue at a time?

The error could be in one of those files.

Yes, deleting one row at a time... the hole content of the file..., it just works again when I delete the file itself.

OMG... yes, I had two blank lines after the closing php tag that were causing the error. Thanks a lot!

You are welcome. That is why I leave the final closing PHP tag off.
