Nextcloud after update not reachable(HTTP ERROR 500)

ℹ️ Support

Dear community,

since my PHP version was outdated (5.x) I had to update to version 7.2. After updating Nextcloud to version 13.x via the automatic updater in the backend, Nextcloud is no longer reachable. When I go to the website only a blank page appears and Chrome reports a “HTTP ERROR 500”. What can I do now?

What information do you need from me?

I would be glad about a quick help. :roll_eyes:

Nextcloud version (eg, 12.0.2): i think it has been updated to 13.??
Operating system and version (eg, Ubuntu 17.04): running on an external Webspace
Apache or nginx version (eg, Apache 2.4.25): latest version
PHP version (eg, 7.1): now 7.2

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Y
