Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.

You have a lot of errors from the Polls app in the log. To narrow down the problem: Do both apps, Activities and News, start working again once you disable Polls?

Thank you @mritzmann . Indeed, also the Polls app throws in the Web-UI such an « Internal Server Error». Disabling Polls enables Activities to start working again, but not the News app !?

It sounds to me like something went wrong when the polls and news apps were updated. I would try the same with the news app: disable, and re-enable it. If that doesn’t help, could you post the current error messages from the nextcloud.log again?

Thank you for the suggestions. Disabling-re-enabling did not help.
So I went for removing and re-installing the concerned NC-apps. After fixing database missing indices, and a complete system reboot => no more «Internal Server Error» :smiley:
