This issue appears if your hoster configured PHP to use the common gateway interface (CGI) instead of the command line interface (CLI).2 Semantic MediaWiki is relying on the latter.

Solution[edit]

Make sure that you are using PHP from the command line interface (CLI). Contact your hosting provider on how do do this.3
