See for example http://validator.w3.org/check?uri=http://hu.wikipedia.org/w/index.php?title=F%C3%A1jl:Type_A_USB_connector.jpg&filetimestamp=20050425002005 - apparently there is a mismatched div tag somewhere.
The message 'sharedupload' ([[hu:MediaWiki:Sharedupload]]) has syntax error.
Ah, thanks! But shouldn't content errors be fixed automatically by Tidy?
Tidy can be turned off ([[mw:Manual:$wgUseTidy]]) and I don't know its status on Wikimedia.
Tidy is enabled within the WMF cluster, although I do believe it doesn't run over Mediawiki:* namespace due to caching or something (But don't quote me on that)
