Site Categories not displaying categories on 2 subsites only

Hi

I have site categories running well at http://tradr.com/sites/

However, 2 sites are unable to add themselves to categories.

All sites have been network updated, and the plugin is latest with it being network deactivated and re-activated.

Each site has a different error (see images attached).

All the other sites are displaying their site categories ok from the subsite backend.

Any ideas?

Cheers,

Johnny
