subpage content lost on rename

[Alessandro Pocaterra]

I had a page "aaa" and a subpage "supervisor and ndscheduler". I removed the heading inside the body.

I wanted to rename it as "install supervisor and ndscheduler".

It gave me an error (alas I don't remember it, but it said something a not valid name). After the error I had the possibility to change to another title but strangely enough the proposed title was "install supervisor and ndscheduler s" (not the extra blank+"s" at the end).

I exited without changing and the page content was gone. Not I have a "supervisor and ndscheduler" (the original name) with a heading only, as the page was created from the scratch.

If I want to rename it to "install supervisor and scheduler" and rewrite the content it gives me the error "Page already exists".

So the page "install supervisor and scheduler" is somewhere but not visible in the index, nor through search.

It is not possible to export the db to HTML: the last screen reads BACK/FORWARD when it should be BACK/OK (I do it often and I remember this). There is no extra page after selecting the HTML file name so it stops there without the possibility to move on.

I also got this error:

***************************
* EDIT: After restart it is saved as PAGE and moved accordingly in the index.

It is not possible to move it back under "aaa", not even after renaming it to "install supervisor and ndscheduler".

Now it is a PAGE in the main index with the new name.

It has been moved to PAGE and a random subpage was under it. I assume there is a PROBLEM with the tree indexes.

It is possible now to export the db to single HTML.

Something strange again: leaving the page open and doing nothing (I am writing this issue) I see that every few minutes a (gray?) hint box moves very fast from the top to the bottom of the index. It is to random and fast that I cannot read it.
It looks like the index is continuously refreshing, as it does after a change.
