Thread:Project:Forum/Infobox not working/reply (12)

You have a call to Template:DIY, which exists. But Template:DIY has a call to Template:Infobox website, which doesn't exist. You still need that template.

Unfortunately, documentation of the export and import processes is pretty bad. You could just directly copy the source of wikipedia:Template:Infobox website into your wiki, but that makes license compliance difficult. That's why I haven't suggested that method. It is possible to import into your wiki with full attribution, but it's not an easy process to explain.

Oh, and you also need install Extension:ParserFunctions. You said you downloaded it, but I can see that it's not installed yet. Make sure to follow the installation instructions on the page.
