Problem: I am not able to find any fields from my Repeatable Field Group (RFG) when I try to select a dynamic source for a Block.
Solution: If you want to loop over RFGs, you'll need to use a View. Some blocks are designed to work with fields that allow multiple values, but not individual fields in an RFG. The type of block you are trying to insert will determine which type of "repeating" field is allowed for dynamic sources.
Problem: I would like to use a custom field from a related post to generate a dynamic link in the child post template. The Types field shortcode for this field is not returning any value.
Solution: You can use the Types field shortcode to output information from a related post using a special syntax in the "item" attribute, like this:
Problem: I have created a custom field group and applied it to a custom post type. After migrating my site to a new host, when I edit those custom posts in wp-admin I cannot see the field group. If I open the Screen Options tab, the field group does not appear in the list of available field groups for display.
Solution: This appears to be a server-side caching issue. Resave the field group(s) in Types > Custom Fields > Post fields, flush the object cache using the 3rd-party object cache system controls, and the field group should appear as expected when editing these posts.
