I would like to add vcf files to the allowed file types to be able to show links to vcf files on employee presentation pages
I can't find where to change the list of allowed file types in WP single site
In WP multisite there is a whitelist in network admin -> Settings -> Network settings (Upload file types), but adding vcf to this list doesn't seem to change anything.
I am using W3TC cache plugin
So I really have 2 questions:
IF (WP multisite): Why doesn't my blogs react to adding vcf to the Upload file types list?
IF NOT(WP multisite): Do I really have to activate multisite on a single blog to get access to changing the Upload file list?
