Hi, is the acf_form_head() function called before any HTML output? As explained in the docs, the acf_form_head() function is used to process, validate and save the submitted form data created by the acf_form() function. It will also enqueue all ACF related scripts and styles for the form to display correctly.
This function must be placed before any HTML has been output, preferably above the get_header() function of your theme file.
