Why Does My Campaign Keep Appearing After Unpublishing It?

If you've unpublished your FireBox campaign and it keeps appearing on your site, the common ways that this may happen are:

• Verify that your campaign is unpublished under FireBox > Campaigns
• You're using WordPress.com and have enabled caching. Go to your site's Settings > Server > Caching > Clear all caches > click on the "Clear all" button.
• You most probably have a WordPress plugin for caching enabled, try clearing its cache
• If you have a server-side cache (such as OPCache), clear it as well

Now re-try loading your website, the campaign should be hidden.
