I tried multiple time to delete all possible cache (critical css, cloudflare and Chrome) and didn't work.
But file with code is:
pencidesign/customizer-style.min.css
Seems not to be cache file. Rather than a wrong setting.
I tried to restore backup and went but can't do it deleting all the rest.
I deleted (hoping not to do damages) the line:
a:after { content: " (" attr(href) ") "; font-size: 90%; }
from here and it worked.

Sry for inconvenience due to my template experiments :) and have a nice day,
Vincenzo Serino.
