I added the following CSS to "MediaWiki:Common.css":
/* Echo * /
#pt-notifications .mw-echo-notifications-badge {
background-color: #fff;
}
#pt-notifications .mw-echo-notifications-badge.mw-echo-unread-notifications {
background-color: #fab951;
}
As a result nothing happens. No caching involved neither on the wiki nor at the client side. Other CSS adaptions get through immediately. I am pretty sure that I picked the correct classes so I am utterly puzzled for the reason why nothing happens ... This is pretty frustrating so any help is appreciated. Thanks and cheers
