    Getting a Security check message after clicking the download button. Everything to that point worked fine.

    We are running PHP version 5.4.20. The same error when testing in Firefox and Chrome on Windows 7. This is a sandbox site on shared hosting @ BlueHost.

    The plugin uses nonces for form security. You can read more about them here.. http://codex.wordpress.org/Glossary#Nonce

    This typically happens after you install and are testing. The browsers cache the pages. You go back to the page, wordpress serves up a new nonce but the browser serves up the cached page with the old nonce and you get a security check. I have only run into this problem when I'm testing, going back and forth, back and forth etc.
    This will never happen to a typical visitor.

    If you clear your browsers cache, that should solve it.

    Also, if you are using a cache plugin like W3 Total Cache or WP Super Cache it can happen in reverse.
