If you are using a form to create a post, and you have mapped the post content to a View, you will not be able to edit the post content through your WordPress admin. The post content will be filtered by the View that it is linked to. If you would like to break the connection between the post content and the View so you can edit your post through the back-end, you may add the code below to your site. Please note that when you break the connection between the post content and a View, then any changes made to the View will not affect the post content.

In the code below, replace 156 with the ID of your form.

This example requires users to be logged in when they submit entries.

NOTE: You may need to customize this code to work for your timezone
