Auto-activate new users

[Mittineague]

@angelim, you developed that plugin, so could you look at this issue? Whenever I use your plugin, I cannot access the Settings > Plugins page. It just says that there was an error, nothing else. However, when I disable the plugin it works fine.

That plugin has been abandoned
