9.1 Files Page Not Loading After Login and No Navigation

Please help us by providing the following info. Before posting please also check the pinned "Known issues" threads and make sure that you're running the latest available version for your oC release: https://owncloud.org/changelog/

Steps to reproduce
1. Upgraded from 8.2.7.1 to 9.1.0.15
2. Problem occurred after upgrade
3. Upraded to 9.1.1RC1 problem persists

Expected behaviour
After Login the Files page should load listing all files

Actual behaviour
After Login It seems that Files will load but the url changes to apps/files/?dir=/&fileid=30 and seems to be caught in a loop. Icons for the home and plus are redrawn over and over. No navigation to admin or apps or other links can occur.

Special configuration (external storage, external authentication, reverse proxy, server-side-encryption):

Integrity status for oC9+

Login as admin user into your ownCloud and access
http://example.com/index.php/settings/integrity/failed
No errors have been found.

You can just make a copy of the logfile (perhaps we need later some information that is somewhere in this large logfile), then clean the logfile and access again. Then it should show you only the last and important messages.

I shutdown nginx and made a copy of the logfile which was 3MB, then cleared the logfile with "> owncloud.log". Next I restarted nginx and Logged in. Same results. I tried a different user and still got the same results but with a new message notification at the top. It was only there for a few seconds so I had screen captured as quick as I could. The message said "Failed to request notifications. Please try to refresh the page manually. Problem loading page, reloading in 5 seconds" Next, I went to check the contents of owncloud.log. It is still empty. Therefore I have pasted above all the lines of the log file from the first moment I upgraded to 9.1.

Did you upgrade to OC 9.0.4 first? You can't go from 8.2->9.1, because I've seen this:

Updates between multiple major versions and downgrades are unsupported

A mistake I know. The log files tell me I went from 8.2 to 9.1. The upgrade went well with no problems, no errors, and no warnings, and has been working fine since 04 Aug, 2016. I only ran into this problem 5 days ago only with with the web part. All files are being synced through the client.

ownCloud itself refuses to skip major upgrades. What did you finally do to get into your current situation?

I logged in to the web access the same way I do every week when checking for updates and updating my server. Upon login I see this. I am at a loss as to what may have happened. It seems that there is a redirect occurring for some reason. Maybe it has something to do with my nginx configuration for the site. Would you like for me to post that?

Can you describe how you updated? The updater app?

Can you share the version string in config/config.php and in version.php?

I followed these instructions as always for upgrading major releases. Minor releases are done with the updater but for some reason I manually updated to 9.1. It was probably because the updater was not notifying yet about the 9.1 update so I decided to do it manually.
https://doc.owncloud.org/server/9.1/admin_manual/maintenance/manual_upgrade.html

config/config.php (current) version = '9.1.1.0'
config/config.php (backup) version = '9.1.0.15'
config/config.php (old) version = '9.0.4.1'

version.php (current) VersionString = '9.1.1 RC1'
version.php (backup) VersionString = '9.1.0'
version.php (old) VersionStrion = '9.0.4'

I did upgrade to 9.0.4 first. Going from 9.0 to 9.1 I backed up the folder to owncloud-old. From 9.1 to 9.1.1 I backed up the folder to owncloud-bak.

Therefore above:
(current) = owncloud = 9.1.1
(backup) = owncloud-bak = 9.1
(old) = owncloud-old = 9.0

Did you also update your nginx-configuration, it was modified for OC 9.0 and newer:
https://doc.owncloud.org/server/9.1/admin_manual/installation/nginx_owncloud_9x.html

I checked and rechecked other than some commented stuff its the same.

Trying to bump. Here is a screenshot of my issue. Perhaps someone has seen this behaviour before?

I get a similar URL but in my case it is working. Can you have a look into your oc_filecache-table if there is an entry for fileid=16?

For my user it is the entry with path "files", and the storage corresponds to my user (check oc_storages table).

Yes, I have an entry for fileid=16 and it does correspond with my user/storage.

It's really strange that you don't get any errors. Can you check the error console on your browser? And disable add-blockers, script blockers, ... (or try a different system and browser)?

I have tried multiple systems and browsers, even mobile. Three different OSes, Android, and iPhone. Same result on all of them. I have tried with and without proxy and vpn. All the same. I really think it has something to do with my nginx config. I can't think of anything else. There are no errors anywhere.

This problem has been solved. I deleted and recreated my nginx file from scratch and now everything seems to be working fine. I did have to comment out line 88 fastcgi_request_buffering as this option is not available with the stock version of nginx 1.6.4 on debian jessie. Thank you for all the time you spent attempting to help me. :grinning:

I have a similar issue here:

OS Ubuntu 16.04
OC 9.1.0
Apache 2.4.18
PHP 7.0.8

The Web Gui is broken and I'm quit sure, it already worked in this environment. I upgraded to Ubuntu 16.04 a few weeks ago from 14.04.
I can't see my files or e.g. my contacts, see screenshot.
Access via Android app or WebDav and syncing with the Windows tool works without any problems.

Please create a new thread about this issue. The one of the OP was caused by a wrong nginx config where you are using apache.
