Pronamic cookie wall page stay active after accepting cookies in multisite

Plugin: pronamic cookie wall
version: 0.3.1
Problem: The cookie wall page will not remove after accepting the cookies in IE and Chrome for a multisite website.

Multisite:
With Chrome and IE the cookie wall page will not be replace by the site page when clicking the accept button. In Firefox we get the site after clickin the accept button.

Singlesite:
With Chrome, IE and firefox we get the site after clicking the accept button.

Possible solition:
In the file blocker.php (map: wp-content\plugins\pronamic-cookies\views) we add the next row in top of the file.
‘<?php nocache_headers();?>’

Test result:
For the cookie wall page no-cache is used in the browser. After accepting the cookie the defauld cache settings are used for the website pages.
In Chrome, IE and Firefox the cookie wall page will be replace by the site page after clicking the accept button.
We tested this only in the multisite websites. In a singlesite this still have to be tested.
