Blogs MU Theme Options Inaccessible

Hello,

On a WP 4.0 multisite installation, the theme options panel is greyed out and inaccesible in Blogs MU 1.4.5 (parent and child)

I switched between the parent and child and cannot access the option settings in either.

The SAVE ALL OPTIONS and RESET ALL OPTIONS buttons are active and clickable, but none of the settings tabs are.

Can you assist?
