header already sent, problem with register_activation_hook

This is my first question so bare with me.

I have a problem with building a wordpress plugin.
I’m just trying to start but I’m getting an error at a very beginning. I have a problem with register_activation_hook() function, where it produces an error that I can’t fix.


defined(‘ABSPATH’) or die(‘You dont have access to this file!’);

class JobApplicaions
function activate(){


function deactivate(){

function uninstall(){


$jobApplications = new JobApplicaions();

register_activation_hook(__FILE__, array($jobApplications, ‘activate’));

register_deactivation_hook(__FILE__, array($jobApplications, ‘deactivate’));

And an error I get:

The plugin generated 237 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

I can’t seem to find a solution?
