Trisha,
Thanks for your response. I finally figured out the issue, and it had to do with the fact that I had a custom user editor with the User Role Editor plug-in. I was limiting users to editing a single page (so a page with a single post_id), and it was excluding all other post-types, including the page to post a new event. I added a line of code in the functions.php file and all is well with the world. Here’s the workaround for anyone else with a similar issue in the future:
