Activating plugins, viewing pages.

After install, I cannot activate any plugins. I get the notice:

  • Form is missing __token or __ts fields

Additionally, when clicking on "Statistics, Users, Settings" links are unresponsive. This occurs on MAMP and live server. Both on Mac: Safari, Chrome, Firefox, and Windows: Firefox, Chrome, Edge.

Additionally, when I try to click on an activated plugin, I get:

"You cannot access AJAX views directly"

I had no problems with the previous RCs.
