Guest Entries ignores redirect field? I'm looking into a project another developer has done, and after submission of a front-end form the system is ignoring the redirect set in the template. The form is being submitted and saved correctly though. 

Anyone got any ideas why this would be?

&lt;form method="post" action="" accept-charset="UTF-8" id="download-subscribe"&gt;
    {{ getCsrfInput() }}
    &lt;input type="hidden" name="action" value="guestEntries/saveEntry"&gt;
    &lt;input type="hidden" name="redirect" value="/downloads/available-downloads/"&gt;
    &lt;input type="hidden" name="sectionId" value="11"&gt;

    &lt;div class="field name"&gt;
        &lt;label for="firstName"&gt;First Name&lt;/label&gt;
        &lt;input id="firstName" type="text" name="fields[firstName]"&gt;
    &lt;/div&gt;

    ...

&lt;/form&gt;


Possible complications, which i expect aren't a problem but might be worth knowing:


The form is in an include rather than in the template directly
The form is being spat out mid-way through a matrix loop (i.e., if the loop is count 2 then first spit out the form).
Answer: As Brad guessed; the problem was a plugin, specifically Sprout Invisible Captcha. Disabling that allowed the form redirect to work properly again.
