Weird, but I think I know what's happened here. Would you mind checking (via sql) who's RSVP'd as going to the event?

Would you mind checking (via sql) who's RSVP'd as going to the event?

It was a fatal Error, so didn't reach SQL, and thus the users action not taken/recorded ....

mysql> select * from xf_nf_event_response where event_id = 2775;
+-------------+----------+---------+----------+---------------+---------+
| response_id | event_id | user_id | response | response_date | alerted |
+-------------+----------+---------+----------+---------------+---------+
|        3805 |     2775 |   28962 | declined |    1545371936 |       0 |
+-------------+----------+---------+----------+---------------+---------+
1 row in set (0.00 sec)

The event was also Dec 22nd, so RSVP'ing on Jan 30th shouldn't have been possible.

I can't reproduce this unless I manually hardcode some bad data to trigger it. Does this only happen on one event? If so, could you link it?

Does this only happen on one event?

No. Here's another ...

  }
  ["_POST"] => array(0) {
  }
}

This is an event from Apr 23, 2017 at 09:00 → 17:00 ! The only responses URL I can find on the page (both hyperlink and within HTML code) is /events/another-epic-sunday.2527/responses?type=declined with the type parameter.

If i visit the URL with parameter - /events/another-epic-sunday.2527/responses - then I get an 'HTTP ERROR 500' displayed in my browser and an immediate error log entry for it.


And another for a different event ...

  ["_POST"] => array(0) {

}

Strange parameter on that URL? Is that something that could be generated from this add-on, or is something really strange hitting that URL? Hack attempts?

RSVP isn't open/applicable for this event!

It's nothing related to RSVP.

I've sorted this now in the next version, thanks!
