Thread:Project:Current issues/Page creation glitch

When I tried to create a new userpage, I got this peculiar problem: File:Bobrayner pagecreation problem.jpg Any suggestions?
 * MediaWiki is trying to warn me that I'm creating a new page, but this notice can seemingly only be triggered by users who willingly click on the "Create" link or similar (not just by navigating to a currently-redlinked page), so why is a warning necessary?
 * The notice is malformed and unreadable, apparently due to being put inside a narrow frame which takes up the left half of the notice area, and the leftmost strip of the warning is devoted to a pointless image which only takes a small % of the vertical height.
 * Also, on trying to search this page for any related issue, I get " ". Sorry if this is a duplicate.
