 I held off upgrading to 6.8 because of the multisite issue with older
 sites. I saw that bug was fixed in 6.8.1, but on upgrading I saw this
 error:

 Strangely, the side admin bar renders, but the top admin bar doesn't.

Comment:

 I'll move this to the "Role/Capability" component, but the issue involves
 `switch_to_blog()` in the toolbar's `wp_admin_bar_my_sites_menu()`
 function.

 Do you find the error on any page (administration and/or front end), or is
 it only certain pages?
