Scheduler feature caues "oops page not found" error

Does anyone else experience this or have a fix? Since I don’t see much on google about it I’m assuming its something I’ve messed up somehow.

Whenever I make a change to a page and then use the scheduling feature to set the change to occur in the future, anyone navigating to the page (before the change actually occurs) will see an “Oops this is embarrassing” type message. Once the scheduled change goes through, the page renders fine again.

I’m completely updated. I’ve tried several different themes including the standard 2015. I’ve changed the time settings to UTC-4.(Im on the US east coast.) (Although for some reason it won’t change off of military time.) I’ve tried disabling all plug ins.

I’m pulling my hair out here because I cant run this site very well if I cant schedule changes to posts/pages etc..

Any help or thoughts would be very very appreciated!

Thank you!!

(PS if anyone wants to see this in action, I’ve scheduled a change to take place on Sept 9, at 13:00 on a test page. It can be found at: intheboatcomic.com/test-page2)
