When I use 'Numbered Headings',
'no or invalid license' messages appears.
I used that function until few weeks.
But I can't use Numbered Headings function now.
I have another account and another space(It's also free space).
In that space, I can now use Numbered Headings now.
How I can use Numberd Headings option in my space( https://lawai.atlassian.net/ )?
