I have an event on 21.02 and have created an entry for it in the calendar. Now I also created a video and posted it on YouTube. I also wanted to add this video to the entry. Since then, however, I have the problem that in the tab News and Dates when I click on an entry the message “Oops, no entry available.” comes.
This text is also with every entry that I create new, I have already deleted the entry with the YouTube video, but no improvement. You can also have a look at it yourself at Grüne Dinkelsbühl.
