I just want to change the copyright notice. We have XWiki 0.9.840. I have Admin rights. This is what I did:
1 create brand new space by linking to it from elsewhere: [Research.Proposals]
2 hit ? to create that page ...view/Research/Proposals
3 Select more actions/Space Preferences/Presentation
4 All fields are shown empty. I assume this is interpreted as "use XWiki preference for this field"
5 I write "Copyright <company name>" in the copyright field
6 Hit Save Preferences
7 Go to page just created and reload.
Result: copyright notice still not changed in that space.
