Grav in subfolder with root URL

I followed the instructions on this page (https://learn.getgrav.org/advanced/change-site-url) as it says in scenario 1, but Css images and javascript do not load

anyone can help me!?

I am just facing the same issue.

I suppose there is an issue with the given theme's configuration. It is probably configured in the template php files with relative paths to the js/, css/ resources. Probably have to change to absolute, but have not tested yet. I rather move grav out of subfolder, seems the lesser task.

I just tried following the scenario 1 example on that page, and it works fine. I am trying Antimatter. Which theme are you using?
