2.8.6 Upgrade problem resolved

I have done some research on the issues that I had with the upgrade to 2.8.6, and resolved them, the culprit was headspace2 seo plugin, when I acivated it I lost my page navigation, along with my widgets, I reverted to all in one seo platinum, and the problem is resolved, it’s a much more robust seo plugin, but it needs work still to be used with the 2.8.6 upgrade.
