table of contents empty for no reason

[Thomas]

Yesterday I got a problem with TOC being empty. Finally I could resolve it be recovering my outline numbering as stated in a openoffice forum:

"Go to Tools>Outline Numbering and in the Numbering tab, set Heading x to each level x missing (1 to 3). Then update the ToC."
https://forum.openoffice.org/en/forum/viewtopic.php?f=7&t=41946

All the numbering down to level 4 had to be redefined.

I save in Word document format, but as I see it, the outline numbering is a generic office setting, really don't know why it got lost.
