Uninstall / delete OwnCloud from Webspace via FTP

Hi Guys,

unfortunately I have two OwnCloud folders on my webspace (installed it twice). One of the folders can't be accessed through OwnCloud anymore and I can't delete the folder from my Webspace via FTP.

I am pretty new to OwnCloud and I hope someone can help me. How can I delete the whole OwnCloud folder from my Webspace through FTP?

Normally you delete the folder and the database. Why you can't delete via FTP? Probably a permission problem (files created via php have different permissions than your FTP user). You probably need to ask your admin how to solve this problem or check the documentation of your provider for such cases.
