Themes with no options page

Last friday, I upgraded our Multiblog platform ( to WP 3.0. Everything seemed OK. Today I've been upgrading some themes, and I've noticed that blog users can't access to the options page of themes which have this functionality (Tarski, Arjuna X, Atahualpa, etc.). On the other hand, super admin problem can access those option pages.

Yesterday evening I was trying Supporter plugin. After a while of checking, I deleted the plugin. Can there be some relation between Supporter options and the problem I've described above?
