Error with function in functions.php?

Question

I am using the below function in my custom theme to load posts via AJAX. But for some reason it is breaking the WP ADMIN WIdget Drag and Drop and also showing the White Screen of Death when I uploaded the theme to a live server.

I can't figure out what is wrong I am doing. I have no white spaces on my fucntions.php

<?php
function mm_get_all_informations() {
?>

    <table class="table results">

Answer 1

These two lines are wrong:

add_action('wp_ajax_get_data', mm_get_all_informations);
add_action('wp_ajax_nopriv_get_data', mm_get_all_informations);

You need to quote the function name:

add_action('wp_ajax_get_data', 'mm_get_all_informations');
add_action('wp_ajax_nopriv_get_data', 'mm_get_all_informations');

If you had debugging enabled, as you should when you are working, you would have spotted the problem immediately.
