On a wiki where anonymous editors are not allowed to create pages e.g. Commons
$wgGroupPermissions['*']['create'] = false;
A user will be misled into thinking that they can create a page.
They will only be informed upon writing their article and hitting save.
Expected:
- Icon should be marked as locked so the user knows that editing may not be possible
- When clicking the edit icon they should be informed it is not editable e.g. they should only be able to view source.
