As I wanted to avoid manually installation I have tried changing the permissions of the folder and files inside /www/domains/digitalscreen.com.0/public/wp-content/languages/wpml,
but since my 1st option did not work, I had try the 2nd one:
I have finally uninstalled all plugins and manually installed the WP core.
For this process I have downloaded the files from wordpress.org, used Filezilla to first delete wp-admin and wp-includes files, then uploaded the whole files in wp-content (overwriting all files), I have overwritten index.php file and finally uploaded the new wp-admin & wp-includes files from WP 6.2.
After that I have reinstalled all the pluggins, activated them one by one and… voilà! The page is doing well again!
