Allow CORS in Wordpress getting meetup API
<p>Im having trouble allowing cross site. I am adding meetup api into some wordpress pages. 
I added the header and .htaccess, respectively.
<code>header("Access-Control-Allow-Origin: http://domain.com");</code></p>

<p><code>Header set Access-Control-Allow-Origin: http://domain.com</code></p>

<p>I have themes and other plugins installed. Is there a particular place I am suppose to insert the headers? Not sure where else I should look.</p>
