Fatal error getting 'aToxidCurlSourceSsl'

[slackero]

Happens only in SSL mode. Seen on Oxid 4.7.x.

PHP Fatal error: Call to a member function getShopConfVar() on a non-object.

Function should be getConfigParam() instead of getShopConfVar(): $aSslUrl = $oConf->getConfigParam('aToxidCurlSourceSsl');
