Problem solved. I had a couple of fields still set to require and I wasn’t filling them in, so it wouldn’t let me save. Easily fixed, but that behavior might be more prominently mentioned or even have an alert box to say why it won’t save. Otherwise, the plugin is pretty good and easy to use.
I’m also having the same problem. On the Events add page, the Update button is disabled. Oddly, it is enabled on the ‘Calendar installed’ event that automatically creates itself during installation. I can add events by hand through inserts to the database, and I was able to delete the ‘Calendar installed’ event so my d/b connection must be okay. ???
How did you resolve this error? I have the same one logging in to a new WP installation. Thanks
