It was because in my LocalSetting there are these 2 lines : $wgGroupPermissions['*']['viewmywatchlist'] = false; $wgGroupPermissions['*']['editmywatchlist'] = false; after replacement by $wgGroupPermissions['user']['viewmywatchlist'] = true; $wgGroupPermissions['user']['editmywatchlist'] = true; the orange bar ''you have a message'' is correctly removed after reading and the preferences "notification tab" is displayed only when the ''extension:echo'' is installed
Mediawiki-1.23.5 is installed
the wikisysop send a bienvenue message to a new user.talk page the new user see an orange bar given him a notification but this notification cannot be removed.... it always appears on each page
my installation doesn't give a preference notification tab ? there is no red icon with a notification number next to user name as on this wiki What I have forgotten to installed ? Thanks for your answering
