I've changed my board url to a new URL and the Xenforo logo still points to the old URL. I'm not sure why, I didn't edit any templates.
Does anybody know if this is a bug
what are are you using npm for? You could modify the php83.dockerfile to install NodeJS and then use npm to install additional packages in the image. This will’s result in an container image that runs php, has the extensions needed to run XenForo and it also has some npm packages.
