[Owncloud] How to manually disable misbehaving app without reinstalling owncloud?

[Emre Erenoglu]

Hi,

I just enabled some 3rd party & internal apps in my owncloud (ie the
webdav auth and some others), now I can't reach owncloud anymore, it
gives a 500 Internal Server error.

How can I see the list of apps and disable the ones which I enabled?
I could not find any such file in the config directory or others.
