Thanks a million mcfreder, it was the db_version problem. I skipped one WP update so maybe that caused the problem.
Pasting your solution here for others that come across this.
“I had to enter PhpMyAdmin and update manually the db_version in wp_options (https://prntscr.com/6yqm5l) with the version number from the latest wordpress download package (https://prntscr.com/6yqnew).”
