The search bar that is always at the top of the page in the staff interface disappears when we access the 'Manage two-factor authentication' page in our account. To test: 1- Enable the TwoFactorAuthentication syspref 2- Go to your account (click username at the top right and choose 'My account') 3- Go to More > Manage two-factor authentication --> Search bar is not visible anymore Similar to bug 31153? In that case the include file was not the right one...
Looks like it's fixed now (maybe by bug 30952?) Please reopen if I am wrong!
