I have set up a custom post type on my WordPress site using CPT UI, and want my posts to show Excerpt and Featured Image features. These are showing when I edit, but not when I publish (See screenshot).
I made sure to add featured image and excerpt functionality when setting up the custom post type (again, see screenshot), but this hasn’t worked. I can see that next to the checkboxes it says “Featured images and Post Formats need theme support added, to be used.” I’ve tried following the links and tried adding the code using Insert PHP Code Snippet but this hasn’t worked. I’m not confident enough to edit the actual functions.php file of the site, the person who set up the site previously created custom post types and enabled featured image and excerpt, which are showing successfully – but I have no idea how they did it and can’t ask them!
Any help would be greatly appreciated. If there’s no way of achieveing this without editing functions.php file then I will do this – would appreciate if anyone can share any introductory articles to help me do so without crashing the website!!… Thank you in advance.
