That is odd.
YES, I’ve deactivated all other plugins to check for a plugin conflict.
YES, I’ve reverted to the 2011 default WordPress theme (with other plugins still deactivated) to check for a theme conflict.
It looks like you noted having already run through our regular troubleshooting steps which is awesome. Can you confirm that that did not result in you uncovering any conflicts with other plugins/your theme?
I’m also curious as to if you repeat those steps again – and create a fresh recurring event the same thing happens.
Can you confirm?
Thanks!
