Tell us what you are trying to do?
I am creating a frontend form to enable users to post on the site. All works well now after receiving some help yesterday. Still stuck with one thing: I can not find how/where to include a field to add a featured image to a post. As the featured images are important for the layout I need to find a way to enable this. I guess I have overlooked something so if you could give me a pointer it would be much appreciated

It is likely that the featured image field wasn't included in the default fields and is not available to add to the current form because the settings for the custom post type do not specify support for featured images.
Edit your custom post type at Toolset > Post Types and under "Sections to display when editing..." make sure that Featured Image is checked (screenshot).
If it is the built-in Posts type then it should certainly be included in the form automatically, and if it were not it should be available in the Post elements section to drag and drop into the form (screenshot).
But the fact that it is not added automatically suggests something else is interfering in the process.
Could you please disable all non-Toolset plugins and switch theme to twentynineteen then try again to generate a form to publish Posts. If it now works then it should be possible to determine the source of any conflict by a process of elimination.
Let me know how that goes so I can see how to proceed.
