Summary of the issue you are facing:

I have a couple of event series and delete every single event when the task is finished. Sometimes I postpone single events. Now, I can only delete or alter the entire series, not a single event.

I think a general Update to a current Nextcloud version was executed by my host, there’s probably any coincidence.

My now reduced menu when editing an event:

I can’t edit single events and for any unknown reason, the menu items are in English (should be German)

Steps to replicate it (hint: details matter!):

Log entries

Nextcloud

Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.

it is hosted, I can't provide that

Web Browser

If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.

PASTE

Web server / Reverse Proxy

The output of your Apache/nginx/system log in /var/log/____:

PASTE HERE

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

PASTE HERE

Apps

The output of occ app:list (if possible).

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.

Possibly something Calendar related: Cannot edit first occurrence of recurrent event without changing entire series · Issue #8990 · nextcloud/calendar · GitHub

Thank you - same here. Nevertheless it’s a new series or an existing series - I can only save/delete the entire series, single entries are not editable

2nd effect: this part of the menu (save/update/delete…) is in english although I have a German setup

Same here. It is a new “feature” (aka bug) that was introduced with one of the last updates of the calendar app.

A working workaround (for me) is the use of the OneCalendar Android app on my smartphone (which syncs with my nextcloud). In OneCalendar, I still can modify or delete single events in a series, and these are synced back perfectly to my nextloud.

So it seems that it is not the functionality of event series that is broken but “only” the user interface…

obviously that’s my problem — thanks for the hint and link. This will drive us crazy when it’s just about marking recurring shared tasks as “done” (aka delete them) or postpone them in the common family calendar :wink:
