Thank for your advice about paragraphs (the excerpt scrubbed double space, so I forced it non to).
The forwarder is for addressing to the site subdir, since WP isn't in the root directory of the domain.
My naive question is about why a site that was ok for a year, all of a sudden doesn't work well, although I made no change.
Is this possible?
I'd like to understand if I can do something to resolve the situation, modifying for instance the .htaccess (no idea how to), or if the problem is about server configuration, out of my control.
Thank for your precious and skilled help...
