Using the pages module, I have a number of entries that load at domain.com/url_title, for example, domain.com/contact
{exp:channel:entries channel="main" dynamic="on"
disable="categories|member_data|pagination|trackbacks"
limit="1" url_title="{segment_1}"}
<h1>{title}</h1>
{body}
{/exp:channel:entries}
Pages display fine. The contact page has a FreeForm form that redirects to domain.com/contact/thank-you, but gives a 404 error. The pages URIs are set correctly. What gives?
