Hello – I looked at some other posts and when I set a default form I was able to edit existing posts. However, I saw this thread: https://wedevs.com/support/topic/i-dont-know-how-to-edit-this-post-i-dont-have-the-form-id-2/

I didn’t see that the question was answered, but this is my issue/question (the same this user).

For all existing posts (prior to installing this plugin), we need to use or at least MIMIC the original form used to create & edit a post as normal (e.g. when I click “edit” go to the edit post page and not a WP user frontend form). If there is NOT a way to do this, then I think I can create a form that is essentially a copy of the interface and then if the admin needs to use further tools they can access the post via the dashboard.

Just wanted to make sure I am understanding what is happening.
Thanks.

We’re experiencing this exact thing using the Pro Version. We installed WP User Frontend Pro Verson 2.3.2 and are unable to edit posts. Same error as original poster.
