Common issues

On every major upgrade it is recommended to do a full upgrade by deleting all files and folders within your installation directory except /data/ and /config/ and then extract the new code into this installation directory. How to do a full upgrade can be found at the documentation:


Updates between multiple major versions and downgrades are unsupported.

Fixed Bugs

There are various incompatibilities with PHP7 known. Especially the shipped SabreDAV library 2.x in oC 8.2 is not compatible with PHP7. More resources:

https://github.com/owncloud/core/issues/21461 -> WebDAV issue
https://github.com/owncloud/core/issues/21309 -> Calendar/Contacts issue
https://github.com/owncloud/core/issues/21095 -> APCu issue (stripped page)
