Allow Plugins Error During Setup

When setting up a new installation of Contao 4.13 there has been instances of errors on June where Composer will stop with an error saying your trying to install a plugin which isn't allowed. In order to fix this you need to first add the code below to the composer.json file then delete the 'public_html/vendor' folder and rerun the installation. This will allow you to continue on through to the end.

"config": {
	"allow-plugins": true
