Look at the Wiki page at the given URL. The page shows <source> tags and does not proper format the Basic code. Perhaps <source> does not work and <syntaxhighlight> has to be used?
It used to work. Maybe a MediaWiki extension is missing. ->Dennis
yeah, correct. I was cleaning up unused extensions and my analysis original showed, that syntaxhighlight wasn't used. Strange. Something went wrong as it seems.
Reasctivated. Thanks for reporting.
