I'm moving my wiki from https://sourceforge.net/userapps/mediawiki/tengstrand/index.php?title=Main_Page
(SourceForge is closing down this service) but the logo don't show up. I have tried to follow the guide http://hub.wikkii.com/wiki/Newbies_Quick_Guide
but nothing works. The logo is uploaded at http://laja.wikinet.org/w/images/laja/uploads/7/70/MediaWikiSidebarLogo.png
I have managed to move all other content except for the logo. I would be very glad if anyone could help me with this!
