I've followed the instructions here: https://octobercms.com/docs/console/commands#console-install-composer to add composer to October installed using the Wizard, but now I get an error:
FatalErrorException in Factory.php line 15:
Class Illuminate\View\Factory contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Illuminate\Contracts\View\Factory::replaceNamespace)
Any suggestions?
