Yes, I have updated the included plugins.
I have a local server (MAMP PRO) to stage the update and test if nothing is broken before update in production.
It’s appear this problem is only in stage, while in production works fine.
So, it’s strange, but not a big deal.
Thank you,
I have update to the newest version (2.5.2) and the problem seems to be fixed.
Sadly this new update bring a new problem: if I try to accede to appearance > customize; I get “Internal Server Error”.
But if I switch to Twenty Nineteen the page is working.
