I am having a similar problem.
I just installed contact form 7 version 3.3, and I am pasting the short code from my wordpress admin into a custom page.
Here is the code I am pasting in:
[contact-form-7 id=”180″ title=”Contact form 1″]
Instead of showing up as a form, I get this:
[contact-form-7 404 “Not Found”]
I have Contact Form 7 3.3 installed and wordpress 3.4
Initially, I had ‘Contact Form 7 – Customfield in mail’ installed, but I de-activated that too see if that was the problem and nothing changed.
I have also tried pasting this code into HTML, but had no luck there either….
I looked for contact form 7 version 3.2 to see if I could downgrade to fix the problem, but I could not find it.
Any ideas on what might be causing this? How can I correct it?
