Calendar import / caldav sync?

mmm maybe I damaged something ?

Does a page refresh help with this? I think Calendar (currently) won’t automatically pick up changes to events that it didn’t do itself.

it’s even worse: the event disappeared from online calendar (but still in my phone calendar).:scream:
Currently my online calendar seems completly empty.

Does the “runbox” calendar you created on your phone show up on the calendar listing on the left of the page?

I do have nothing below my calendar on the left menu:

I cannot import my “big” ics: last week, it was raising a server error (I reported here: Calendar Import Event not working - #6 by poule)

I retried following your message but I cannot select my calenda (see screenshot below)
