I have a WP multisite installed and I have for the parent and one child blog lost the display of all users as well as the typical user roles that can be assigned.
All the other child blogs seem to be working as expected, just the one child and the parent is acting strange.
I looked in the DB in the wp_1_options >> wp_1_user_roles and the equivalent child location and found data in both those locations, but I also noted that the child blogs that seem to be working file do NOT have a wp_XX_user_roles row.
Any assistance would be great. cb
