I installed a 3rd party extension on Magento2 and followed these instructions: https://store.orange35.com/media/wysiwyg/guides/Image-Constructor-For-Custom-Options-for-Magento2-Installation-Guide.pdf
The frontend layout is now broken, as if CSS was missing... Even after disabling the extension with
php -f bin/magento module:disable Orange35_ImageConstructor
The layout is still broken. How can I fix this ?
