Theme Builder Admin > Global Permissions ---> Javascript Error

Hello,

Just installed latest version of confluence (2.10.1 - evaluation) and theme builder (3.3.3).

Impossible to access configuration tabs (any of them, ex. Global Permissions). Page is blank + javascript error in IE7.

Firefox 3.0.4 -> same issue (no JS error message though).

Is there something I can do?

Thanks a lot!

Diego
