Undefined property: SimpleSAML_XHTML_Template::$languageParameterName

Hi,

I'm using your theme, which is nice compared to the standard.
However there is one thing not working, the language switch.
I get the following errors:

Undefined property: SimpleSAML_XHTML_Template::$languageParameterName

I checked the config, and

'language.parameter.name' => 'language'

is there.
But when checking the languages dropdown, languages= is missing from the link, it only produces &=<language code>
