Server: Files not visible in web interface after upgade to 16

[stone212]

Steps to reproduce

1. Upgrade from 15.x to 16.0.1 using command line updater (sudo -u www-data php updater.phar)

2. Choose to disable maintenance mode

3. Return to nextcloud.mydomain.com which redirects to nextcloud.mydomain.com//index.php/apps/files/

Expected behaviour

I should see my files waiting for me like always

Actual behaviour

I See the NC interface but lots of white space where my files should be. Also I don't have my Files etc menu, now it is a "hamburger" menu but that is not important. It is important that if I choose Files in the hamburger menu I do not see my files.

Strange! I re-booted and the files did not appear. I waited 20 minutes and re-freshed the page and now they appear.

Also the "hamburger" menu is gone and I have icons at the top of the screen.

I have no current problem but I do think this is an Issue/bug to be aware of so I will not close but you can.

[wiswedel]

@stone212 Looks like a caching problem. Is it reproducible? Have you hard-refreshed your browser with ctrl+F5?

[stone212]

@wiswedel It does sound like a caching problem but I tried that many times, also tried opening in a new browser. Then later the problem solved itself. It is very strange.

To re-produce I think I would have to re-install NC 15 and re-upgrade to NC 16.

[wiswedel]

Since the issue cannot be reliably reproduced, I will close this ticket for now. If this is still happening please make sure to upgrade to the latest version. After that, feel free to reopen.
