Apparently the homepage of this website http://www.spe.gov.al/ loads a blank page. Is there a way to browse its subpages?

You can use Google for that. You will, at least, see pages that have been indexed by Google. The commande is: site:www.domain.com:https://www.google.com/search?q=site%3Awww.spe.gov.alIt will returns all indexed pages that belong to this domain. In your case, it seems that all indexed pages are dead except http://www.spe.gov.al/harta/.
