I have WordPress 5.1 installed on one of my websites. I also use Cloudflare Flexible SSL Free Version. I have the Problem, that when logging out of the WordPress Admin Dashboard, and click to a Page on the Frontend of the Website, the Admin Dashboard is still shown (Cached) even if I logged out.
I defined in Cloudflare the following Page Rules:
All Apps and Caching Features are disabled.
When I enable Development Mode in CF, the Issue is gone. When I disable Development Mode the Issue is present.
How I can fix this?
