I broke my settings

[stopthere]

I installed the arcade and also subaccounts using the emulator. Arcade is working fine but subaccounts did not and I uninstalled it. However now when I go to admin and features I get the error

The website encountered an error while retrieving http://www.*************/index.php?action=admin;area=featuresettings;f6824e33385=efa783260ffe3a12801e5c1102ecef76. It may be down for maintenance or configured incorrectly.

Here are some suggestions:

Reload this web page later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfil the request.

It is only when I try to use core features and features  and options. Does anyone have any ideas?

Best option: Restore the backup you took, before installing the mods.
