I don't think that you need to search for an issue in the ownClouds code. The message means that something (maybe old and not deleted code or apps or stuff in your redis/memcache etc.) is declaring a class which already declared previously.
It might help if you explain in detail which steps you have done so far, what previous ownCloud version you're running and the details about your setup. If you're already on ownCloud 8.2 or 9.0 it doesn't make any sense to update to 9.0.11 as you can instantly upgrade to the latest and currently supported version 10.0.7. For this upgrade please follow this documentation step by step: https://doc.owncloud.org/server/latest/admin_manual/maintenance/manual_upgrade.html and especially this one: - Delete all files and folders in your existing ownCloud directory (/var/www/owncloud) — except data and config. - Don’t keep the apps directory. As a side-note: You really shouldn't use versions-specific directories like /httpdocs/owncloud_9/ as there are still quite a few hardcoded path values hidden in ownCloud which you would need to modify manually: https://doc.owncloud.org/server/latest/admin_manual/maintenance/manually-moving-data-folders.html -- Sent from: http://owncloud.10557.n7.nabble.com/Users-f1.html _______________________________________________ User mailing list User@owncloud.org http://mailman.owncloud.org/mailman/listinfo/user
