I have several Custom Post Type and custom fields created with Types. I have been able to display them successfully using Loopbuddy from iThemes. All of a sudden the custom fields stopped displaying correctly (on the front end) only on the pages created within the Custom Post Types.
URL of page not displaying custom fields (within custom post type created in Types) :
hidden link
URL of a page displaying the custom fields correctly (within wordpress Pages post type):
hidden link
Fist image is a page created within the custom post types with "Types" where all the content is not displayed. The second image is a page from the wordpress Page post type where the same custom fields are displayed correctly...
Are you using Types function types_render_field() to display the custom fields?
Here is a document about "Writing PHP code and using Types API to display custom fields"
https://toolset.com/documentation/user-guides/displaying-wordpress-custom-fields/#1
Hope it help
If you need more assistance for it, please describe detail steps to duplicate same problem, and post a downloadable URL for the other theme/plugins which is required. I need test and debug in my localhost. thanks
