OK, trying out some more things and encountering weird behavior:
There was an event post that would not go to Trash when I clicked that link and it remained listed as a Draft. I finally logged in to my database and deleted it manually from there. OK, all garbage removed, tiem to try the Events Calendar again.
Created a new post, marked it as an Event, filled in some date, time, and location info, and clicked Publish.
The screen refreshes and I see the new post in the Edit Posts list but it’s listed as a Draft and doesn’t show up on the website. So I go to Edit the post and nothing happens – the screen refreshes back to the list.
So I try the Quick Edit, which does let me access the post, and I change the Draft setting to Published. But when I click Update Post I get a message Error While Saving Changes and the post remains unchanged.
Once again, I cannot send the draft post to Trash so I’ll have to manually delete from the database again.
What on earth is going on??
