Hi Elliot,
That did it. I have two rows in my wp_options table (as I was testing with two fields). I deleted both rows and my form now submits correctly!
Also, I’m not sure if I should start a new topic or not, but is there a way to change the post_title to pull the value from a field that has been setup? I tried this, but it did not work:
'post_title' => $_POST["fields"]['page_title']
Where page_title is the name of the field I setup in ACF.
Thanks very much,
James
