Thread:Project:Support desk/Upgrade from WM 1.15 to 1.20.3 - Cannot Access User Settings - Global default is invalid for field editfont/reply (2)

Note that writing: $wgDefaultUserOptions = array; $wgDefaultUserOptions['searchNs4'] = 1; $wgDefaultUserOptions['showtoc'] = 1; is the same as $wgDefaultUserOptions = array(    'searchNs4'   =>  1,    'showtoc'     => 1  );

You probably had some other problem.
