Fix WebDav errors
In some cases, you may see the error below in the ownCloud administration panel:
Your web server is not yet properly setup to allow files synchronization because the WebDAV interface seems to be broken. Please double check the installation guides.
That happens when the certificate for your server is not properly setup. Find out how to configure your own SSL certificate.
NOTE: You can continue using the ownCloud Desktop clients to sync files in spite of the above error.
