$EM_Event->save() not working in 5.8.x – okay in 5.7.3

I looked at the database before and after I clicked “Update” in the Edit Event page.

Before:
– No row created in ${prefix}_em_events table
– _event_id is null in postmeta

After:
– Row is created in ${prefix}_em_events table
– _event_id is set to index of this new row
– _event_start_time and _event_end_time have the ‘seconds’ portion set to 0 (this is not a problem for me but just a bit strange).
– _edit_lock and_edit_last postmeta is created.

Version 4.9.1.

From changelog: Maybe these items:
– changed and optimized postmeta saving process to reduce number of rows by up to 80% per event,
– added cache optimization for event and location loading,

The EM_Event::save() code has changed quite a bit between 5.7.3 and 5.8.

Have you been able to try the code I posted?
Put it into a file in the root folder and run that url from the browser.

No logs, just not working.

I ran it again and it generated an error message:

This block of code in classes/em-event.php has changed quite a bit since 5.7.3 (“Update Post Meta” comment at top)
https://plugins.trac.wordpress.org/browser/events-manager/tags/5.8.1.1/classes/em-event.php#L891
It has gone from 16 lines of code to 38 lines and ‘event_rsvp’ is one of the fields in the new code.
