It destroyed all the database I can’t publish new posts or pages!! This the message I see when create new post or page and already doing some troubleshooting but nothing works:
Warning: Creating default object from empty value in /home/customer/www/site.org/public_html/blog/wp-admin/includes/post.php on line 762
Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/site.orgpublic_html/blog/wp-admin/includes/post.php:762) in /home/customer/www/site.org/public_html/blog/wp-admin/admin-header.php on line 9
It does not point to the IW plugin at all. It could be related of course, there are so many different variations of WP enviroments that issues can happen. But it does not mean ruining your site in any way. Just a bug identify and solve.
