Hello !Friendica Support,
can anyone explain to me this post?

The user who seems to have posted it is not a user of my server friendica.utzer.de, at least there is not user "friendica" on my server, not present and also not to be deleted (in the deletion process), so how come this post exists?

I wanted to reshare this post to the support forum, but then the user was chaned to friendica@social.yl.ms.

I think we have some serious bug here!
Well, you do have this user on your machine. It's the technical user with the user id 0. This user is used for some technical stuff like signing public http requests.
@Michael Vogel and why does this user create posts? (calendar entries)

I don't know.
@Michael Vogel every system seems to believe this is a local post, yours probably too.
@utzer @Michael Vogel looking at who shared that event, it is a Mastodon share of an event from Mobilizon..

Here is the Mastodon share https://mastodon.uno/@linux/106526989768614589

But the original Mobilizon. event seems to be deleted in the mean time.
I had the same calendar entry. No idea where it came from. On my side it said I had made this date.

Even the comment is the same.
I also got this mail today from my host:

@Michael Vogel Yes, this seems to be hitting (random?) users - please see https://social.isurf.ca/display/065e484c-0f53-42db-893b-9310bef0b48f

It's kind of scaring some users as well... is there anything I can or should do to help with this one?
I can see that it is a post from Mobilizon. I have to check the processing.
There seems to be a new one incoming: 16th Juli: Accessibilité web pour toutes et tous !
It is this one: https://mobilizon.fr/events/adb0999e-7449-4bec-8d1c-42a04de6fc5a

In Friendica it looks like I am the creator.
@Stefan H. how did you get the event? Do you follow the original account on mobilizon or did some contact forward (boost, whatever) it to you?

I've fetched the item into my system by searching for the URL and it is displayed correctly.
I can imagine that it has been transported via some relay.
It suddenly appeared on my timeline. Going into calendar tells me I have created it. I didn’t. I am not following this account and the only thing I see that a „Thomas Citharel“ from Mastodon has shared it. I am not connected to this person.

Interesting: I also got this error again:

PHP Notice: Undefined index: protocol in /var/www/src/Model/Item.php on line 1039
PHP Notice: Undefined index: direction in /var/www/src/Model/Item.php on line 1040
PHP Notice: Undefined index: source in /var/www/src/Model/Item.php on line 1041
The above email from the worker cron came exactly the same time the post was created on my server.
Heute ging der nächste Termin ein, @Tobias.
same here with events from mobilizon. I got events from mobilizon reposted as my user.
I can delete it, but as soon a comment is sent to it, it reappears...
For now I blocked the mobilizon instance...
Does it happening after my last changes as well?
ehm.. right.. we are on last stable 😁
I'll check
Is this only on your instance or should we all do an update?
"we" as in "the instance of the LUG" 😀
That was meant for @Michael Vogel, sorry.
You can go to the develop branch whenever you want 😀
I see. There it is. Thanks!
@Stefan H. develop is rather stableish at the moment.
so it's developish, also...
Is develop always based on the latest stable? And how to switch to develop?
@Stefan H. develop is always ahead of stable and is merged (via the RC branch) into stable with a new release. So yes, 2021.09-dev is based on 2021.07 (stable) and will become 2021.09-rc and then 2021.09.

If you are using git to manage the code, you can

git checkout develop
git pull


on the terminal in the base directory of Friendica and the addon directory.
Thanks! I will checkout develop this evening. 😄
Ok, changing to develop is done. Let's see if another unwanted calendar entry will show up.
