Hello,
I wanted to say that I got the solution. The problem was related with the “Deprecated: contextual_help is deprecated since version 3.3.0! Use get_current_screen()->add_help_tab(), get_current_screen()->remove_help_tab() instead. in /home/.sites/327/site3737621/web/wp-includes/functions.php on line 5088” issue.
I follow the instructions given in this thread https://kriesi.at/support/topic/error-after-wordpress-update-2/
I hope the new theme updates fix this problem.
Thank you so much anyway.
Best regards,
Fabio
