**Are you using external storage, if yes which one:** local/smb/sftp/...

**Are you using encryption:** yes/no

**Are you using an external user-backend, if yes which one:** LDAP/ActiveDirectory/Webdav/...

#### LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM oc_appconfig WHERE appid = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

/usr/share/php/Sabre/VObject4/Component.php

Most likely caused by this where your used owncloud-httpd-9.1.4-3.el7.noarch (which is not an official package) is using the SabreDAV shipped with your distribution and not the SabreDAV version included in the official packages from owncloud.org.

I think you should report this issue to the packager of your distribution instead of here. An alternative would be to use the official packages from https://owncloud.org/install/#edition which are not showing this issue.

[esarakaitis]

As soon as i disabled the federated sharing, it started working again

[ghost]

Still it worth to report that to you packager. ownCloud heavily relies on the correct used Sabre/* versions. If your distro is shipping a newer or older versions this might break at any time.

[ghost]

Just to show the issue: Your system is currently using/providing sabre/vobject 4.0+:

Starting sabre/vobject 4.0

however ownCloud 9.1.4 needs sabre/vobject 3.5.0:

https://github.com/owncloud/3rdparty/blob/3b3d908e9b1124cb1dd7d2224b6ba6a58f2e2fe9/composer/installed.json#L1641-L1642

Nothing what can be done here from ownCloud side (besides upgrading to sabre/vobject 4.0 at some point in time and make oC compatible with it). Please close here and report this issue to your distro / package provider.

@hodyroff @PVince81 @DeepDiver1975 FYI if further of that kind of reports are coming in here

[hodyroff]

Great catch @kdslkdsaldsal
@esarakaitis where is the .rpm package from?
Closing, you can continue to comment.

[esarakaitis]

looks like its an EPEL package

[hodyroff]

@jnweiger @crrodriguez FYI Don't know what we can do with wrong packages out there.

Another one with the mix between sabre/vobject 3.5 and 4.0: #29663
