What can I do?
Thank you very much for your help.

I’m sorry, the problem is not solved.

This is the problem now, after deactivating the plugin:

Warning: Creating default object from empty value in /web/htdocs/www.eurousc-italia.it/home/en/wp-admin/includes/post.php on line 708

You are right.
Deactivating the plugin I have this problem:

Warning: Creating default object from empty value in /web/htdocs/www.eurousc-italia.it/home/en/wp-admin/includes/post.php on line 708

I have deactivated the SEO plugin and the problem is solved.
Thanks a lot for the support!
