After reading a lot of messages, posts, questions and bug reports that concern the "Oops: document is published but is not in the cache (internal error)" message, I found that a lot of people have this problem in load balanced environments, some have this problem after installing packages, and some others experience this in a simple setup.

I find myself in this last category, but where a lot of people aren't sure about the origin of this error (the message is not the error itself, but a symptom of something going wrong somewhere) and are not able to reproduce it.

This message is occurring very regularly on my site, and I finally am able to reproduce it. If I've missed a post somewhere that already addresses this same scenario, you are welcome to point it out, well possible that I've missed a solution between all the talk about load balancing etc. :-)

To reproduce the error:

• Create a new item
• Fill in all fields, BUT FORGET A MANDATORY FIELD
• Press "Save and publish"
• Umbraco warns you about the field, so you fill it in.
• Press "Save and publish" again.
• Umbraco tells you it's all good: "Content published: and visible at the website"
• Click the properties tab and find out that your item is in fact NOT published when you see the error "Oops: this document is published but is not in the cache (internal error)"
• Only "Republish entire site" fixes this...

So... First question: can someone else reproduce this? If not, I probably wrote some bad code that I will have to smoke out. If so... Next question: what do I do about it?

The exact Umbraco version is: 7.2.1

Thanks in advance for thinking with me!
