Hello, thank you Brian for your support. I had the same issue after updating from 4.0.7 to 4.1.x version today. So I downgrading manually to previous working version 4.0.7 and all is working fine again.
I activated the debug mode in wp before downgrading to previous version and made a test to help you on the event calendar with the current 4.1.0.1 version. I found the following error :
[29-Mar-2016 17:58:17 UTC] PHP Warning: in_array() expects parameter 2 to be array, boolean given in /homepages/15/d388552681/htdocs/wordpress/wp-content/plugins/the-events-calendar/common/src/Tribe/Admin/Notice/Archive_Slug_Conflict.php on line 49
I confirm the issue is not appearing when I’m logged in as Admin user.
Hope it will help.
Regards
