Upgrade to 2.16.1 failed

Support & Bugs
#1

When upgrading to 2.16.1, the webpage never came back. I downloaded the zip file and put it in the piwik folder but now I get the following message on every “dashboard block” or another screen.
“Error: ViewDataTable ID ‘table’ is already in use!”

What is the solution?
