Problem: I would like to clone a post from one site in my multisite network into another site in the same network using the WP Multisite Content Copier Pro plugin. This plugin allows me to clone a post across sites and was working as expected, but recently stopped working.
Solution: In this case exposing the custom fields to the REST API seems to have solved the problem. Manage that setting in Toolset > Settings > Custom Content. Check the checkbox for "Expose custom fields managed by Types for posts, users, and terms through the REST API" and save the settings.
Problem: I've migrated my site to a new domain, and now my image custom fields contain URLs that include the old site domain. I would like to change those custom field values to point to the new domain instead.
Solution: A good 3rd-party site migration tool can handle domain replacements for image custom field values automatically during the migration process. Another option is to export your site's post content using the standard WordPress export process. Once that export file has been generated (it will be an XML document), you can edit it with a text editor like Sublime Text. Use the find-and-replace tool to find all instances of the old site domain and replace them with the new domain.
