Hi @officialsabbirr
I hope you are having an awesome 2018 so far.
The first thing we will need to establish is whether you have the acf_form_head() function at the very top of your page template. The post id that you are passing also suggests that you are trying to modify a certain post, is this right?
Perhaps you could share the complete code that you have in your page template so that I can advise further?
