Problem updating

I am having a problem updating to the latest version using the auto update:
The following error just broke Piwik (v2.1.0):

Call to undefined method Piwik\Plugins\UsersManager\API::getUsersHavingSuperUserAccess()
in /home/medalia/www/piwik/core/Updates/2.0.4-b7.php line 50

My ISP had to restore my piwk to the last version so I could still use it. Any ideas about how to solve this problem? Thanks for your help.

It looks like when you upgraded to 2.1.0 you didn’t upload all files properly. Some files were still using 2.0.3 or so

Thanks for the info. I did it more than once and it didn’t go through. I now have the old version in place - it was rolled back. I used the update automatically feature and I didn’t expect any issues. I use a similar feature with wordpress all the time and never have any problems. What do I do now?
