Hey Tim,
Thanks for reaching out. First, I think it’s worth clarifying that The Events Calendar is not the “standard version” of the plugin, with Events Calendar Pro being a “premium” version that replaces the standard version or is an alternative to it.
How it actually works is like this:
• The Events Calendar is the CORE plugin. It’s free and provides a fully-featured calendar for WordPress sites.
• Events Calendar Pro is a premium add-on to this core plugin. So if you buy and install Events Calendar Pro, you leave it running along with The Events Calendar. It does not replace The Events Calendar, it just activates some extra features of it.
With all this being said, the presence or absence of Events Calendar Pro doesn’t affect the display of past events. Past events are visible by default.
At this time, it’s true that there is not an option to hide past events. It would require custom CSS to do so.
I hope this information helps!
George
