How to Build a WordPress Theme - error on work.php page

Hi guys,

I have two problems building my WordPress Theme.

  1. Whenever I update any of my work pages I get a blank screen. I turned on the php errors and what I get is this:

Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/allisongrayce.com/wp-content/themes/wpportfolio/functions.php:45) in /Applications/MAMP/htdocs/allisongrayce.com/wp-admin/post.php on line 235

Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/allisongrayce.com/wp-content/themes/wpportfolio/functions.php:45) in /Applications/MAMP/htdocs/allisongrayce.com/wp-includes/pluggable.php on line 1121

  1. Also, even though I have my images already in my media, when I am for example on Stop Visual Pollution page and I want to add the images to the post I get...nothing. The little circle, I don't know the name of it :P it keep loading and loading and nothing happens.

Thanks in advance!

I took a look at that pluggable.php screenshot...If your following along with the tutorial you don't need that pluggable file unless you have plans for it. But if you are going to use it. You might want to check out this link. http://codex.wordpress.org/Pluggable_Functions You will have to wrap your function with this ( !function_exists() ) otherwise you will get that error you getting. Hope this helps!

Can you post the code in your functions.php ?

The code that you have a screenshot of looks fine. Can you show me what you have on line 45 in your functions.php file? Also, what part of the tutorial section are you on? That will help me narrow down exactly what section to look at.

Try changing line 24 to this 

wp_enqueue_script( 'theme_js', get_template_directory_uri() . '/js/theme.js', array('jquery') , '',true );
