/event slug brings up no page found using shortcode and selected page for front end interface

Okay got the front-end editor working, but since I activated Cloudflare on my site the page comes up as missing or not able to be found.

Any idea what might be causing this? Also event specific links bring up the same thing, no page found. I can see the event in the calendar and in the sidebar widget, it is also showing in the activity stream but going there does not work.
