On WordPress version 4.1.1 (network installation on PHP 5.2.6) the Sync available page produces the following:
Fatal error: Call to protected method WP_List_Table::set_pagination_args() from context ‘acf_admin_field_groups’ in [serverroot]/wp-content/plugins/advanced-custom-fields-pro/admin/field-groups.php on line 360
Hi @ronansprake,
Thanks for the post.
This bug is now fixed in the latest stable version of ACF.
I am now going to ahead and mark this topic as closed.
