Thread:Project:Support desk/How to reenable the sitenotice/reply

IIrc MediaWiki is somehow saving the state of this notice. Do you see it again, if you remove all cookies related to the according site?

If not, you can still view the page MediaWiki:Sitenotice inside the according wiki, which will contain the text of the site notice. See Manual:Interface/Sitenotice for more information on the pages, which are used for site notices.
