Sorry, it seems the problem is just because the first column is with username with emails. Right? Bug or feature?

Same problem while upgrading my site on Enterprise open source softtare.
The “clear private datas” trick did not work.
The problem was that I did not desactivate plugins.
To solve the problem in in such cases:
– Connect to your database ( via PhpMyAdmin for example)
– Find the wp_options->active_plugins row
– Edit it, and put:
a:0:{}
in that row.
Solved the problem for me.
