I get a fatal error:
Fatal error: Uncaught Error: Call to a member function get_blog_prefix() on null in /public_html/wp-content/migrate-wp-user-avatar.php:18 Stack trace: #0 {main} thrown in /public_html/wp-content/migrate-wp-user-avatar.php on line 18
Anyone who can help?
@philipjohn I received a report of this failing on multisite, where the script only works on the main site and not subsites. Is that a known issue, something that needs to be accounted for in running the script differently, or a user mistake?
