Why do we keep getting that {{Missing cached output! Please contact an admin}} error so often? I punch the <reload> button several times, all to ∅ avail.

Jon

I got the same error twice some days ago while editing an entry.
At first I thought it was my fault for doing something wrong, so I just deleted the entry and entered it back from a backup on my computer.
But now I start thinking there could be a problem of some sort with the server and/or database...

RE:"I got the same error twice some days ago while editing an entry."

Here I was referring to an entry by someone else, which I cannot edit or re-render, but only hit the reload button. Still, I do often get this message on my own entries, and even then the reload and re-render do not always work, and so I have to go back and do a null-change edit, which leads to an excess of apparent versions.

You can rerender any entry: copy the URL

http://planetmath.org/?op=rerender&from=objects&id=XXXX

into your browser's address bar, replace XXXX with the object's ID number, and hit Enter.

Thanks, I can never seem to remember that one --
is it in a FAQ somewhere that I could bookmark?

At any rate, the re*render doesn't always work either,
even on my own entries, and so I have to do a null-edit.

I don't think so. But you could click on the link

http://planetmath.org/?op=rerender&from=objects&id=XXXX

(which gives an error message) and bookmark that - that makes it quite convenient to use.

We are going to look into fixing this bug as part of the summer programming work.
