Im trying to create a post edit link but keep getting the same problem.
Im just checking my process here please
1 I have created a form to edit the post type Vacancy - see image
2 I have created a content template to contain the form to edit post type Vacancy - see image
3 In the Content template that Display the single post for post type Vacancy I insert the toolset form shortcode Edit Post Link and then get the following message - see image
The issue was that you had the layouts plugin installed so the plugin was assuming that the edit form was in a Layout. Disabling Layouts caused this to start working again.
