When I load my wiki, the paragraphs are numbered, without being logged
in, in other words as an anonymous visitor. Then I changed the option:
$wgDefaultUserOptions['numberheadings'] = 0;
Ok, now the numbering of the paragraphs are gone. But when I log in with
my username, the paragraphs are numbered again. How can I change this
option for all users so that is off/zero.
