I accidentally click the close button on a site, how can I enable it again?--一個正常人 (talk) 17:51, 25 February 2015 (UTC)

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.
Each time when I need to see the text or find the link in the sitenotice, I need to view the page MediaWiki:Sitenotice, it's really inconvenient.--一個正常人 (talk) 13:12, 26 February 2015 (UTC)
Have you tried my other tip?
