Security error on user mass action

I get a security error when i try to mass delete users:

To reproduce:
  • Search users with all status checked except confirmed
  • Get over 200 Pages
  • Click show all results
  • Click process selected results

This is likely caused by the post_max_size and max_input_vars settings in PHP.

To deal with that amount of input they will need to be raised a considerable amount.
