I RESOLVED it in this way:
in the index.php in the root i changed this:
require( dirname( __FILE__ ) . ‘/wp-blog-header.php’ );
into this:
require( dirname( __FILE__ ) . ‘/wpfolder/wp-blog-header.php’ );
using text editor on mac BUT WITHOUT WRITING!
i copied-pasted the letters that i needed from other words from the same file.
It worked for me!
So i think this was a font error!
