Thread:Project:Support desk/Fatal Error after installation/reply (5)

go to the  folder and run

Paste this line and press enter:

var_dump( $wgContLang );

And the same with this:

var_dump( Language::factory( 'da' ) );

Paste the results here.

I'd also try to install again from scratch, downloading the tarball again, unpacking, drop the database and create it again from the installer.
