@dazzlindonna – sorry for late response. It was night-time here in the UK and also the authors of plugins don’t get notified of new messages here, which I still find strange.
Anyway, onto the problem
1. If you have WP Super Cache plugin enabled, it does work, but webkit browsers cache a copy for a very long time, so open up a different browser
What theme are you using?
Any caching plugins?
What URL are you testing?
If you would like to try and remedy it yourself, you could try finding line 314 of sopablackout.php and change the ‘template_rediect’ bit of the line as seen below:
add_action(‘template_redirect’, ‘sopablackout_content’);
… to one of the following:
muplugins_loaded
plugins_loaded
sanitize_comment_cookies
setup_theme
load_textdomain
after_setup_theme
auth_cookie_malformed
set_current_user
init
widgets_init
register_sidebar
wp_register_sidebar_widget
wp_loaded
parse_request*
send_headers*
parse_query*
pre_get_posts*
posts_selection
wp*
I would start at the bottom and work upwards (please ignore the asterixes when copying and pasting.)
