Cannot edit new View
If the views are working but you cannot edit, then could something wrong with the views_ui module.

There are two differend modules:


Views: for views functionality
Views_ui: for changing views with the web browser at admin section.


Views do not need the Views-ui module activated. This is only for changing existing views. Therefore you can try to deactivate views_ui module and reinstall it. 

(Cache clearing is always a good idea, but I think this have you done.)
