Pages not loading correctly after domain name change

Hello All,

An existing D7 site changed from one domain name to a new one, and now pages are loading without any formatting except very basic HTML.

I changed the base URL in settings.php, but that didn’t make a difference.

Searching the site didn’t find anything relevant. Any hints as to what I should look for? Is it possibly a directory ownership issue?

Thanks!
