There's an issue with Joomla 3.6.0 where the logout redirection can have incorrect behavior. Please check out this thread on our forums:

This also links to a Joomla bug fix which should be in the 3.6.1 release that you could implement now:
github.com/joomla/joomla-cms/pull/11093/...e8beca96c1d83f3d7d1b
tjones64,
If you're seeing a completely white page, please go into the Joomla Global Configuration area and set Error Reporting to 'Maximum' and see if a PHP error message displays which may also indicate another issue to investigate.
I hope that helps, but if you still have issues, please let us know.
Thanks,
Alex
