I finally decided after some research on google to follow the recommendation to deactivate some extensions… and bingo ! The extension “All in one SEO” was causing the white screen issue… Solved !
I checked that all my add-ons are at the latest version (automatic updates) and they are…
I enabled debugging mode in wp-config.php and reexecuted the appearance -> widgets php … Still have a blank screen, no error message on the screen and the debug file is not created… Help !
