I had the same issue. Logging out and back in solved it with no changes to anything else.

I was using a feature in my theme that redirects 404s to another page. I disabled that feature and installed the “404page – your smart custom 404 error page” plugin instead and that resolved the issue.

Thank you for your help!

Thanks for the quick reply! I believe logging is enabled based on the following settings on the Options tab:
Redirect Logs: A Week
404 Logs: A Month
IP Logging: Full IP Logging
Redirect Cache: An Hour
REST API: Default REST API (Note: I have tried all options here. I have also tried disabling caching and the security plugin)

An invalid URL would be: https://rocstarts.com/badurl

This issue is marked as resolved but the resolution is either to not use shortcodes or downgrade WordPress. Neither of these is a good solution when there are other elements on the page. Is there a solution to keep the shortcode with other elements on the page while showing only one calendar? Even something as simple as adding a separate CSS class to the 2nd calendar would be helpful since it could at least be hidden.

Yes. It is required because there are other elements before and after the calendar.

Is there a solution for this when a shortcode needs to be used on the Calendar Page? Upgrading to WP 4.7 causes two calendars to be displayed (see https://pca.nmvhosting.com/calendar/). Sticking with WP 4.6.1 displays only one calendar (https://niagarapca.org/calendar). Changing themes, deactivating plugins, and switching browsers did not fix the issue.

I was able to resolve this error by unchecking “Filter Suspicious Query Strings in the URL” in iThemes Security (under “System Tweaks”).
