thank you all! it works! now i can choose the hybrid news theme and install it.
thanks for your reply ipstenu!
you mean disable it from the admin panel or just delete it from my “themes” folder? if it is from admin panel, i cannot access it at all, i got blank page…btw this is my folder tree (i want to use hybrid news):
/wp-content
/themes
index.php
/hybrid
/hybridnews
/twentyten
