When I try to access the admin panel of a certain Wordpress site, I'm getting the following messages when it redirects to the panel's index after logging in.
Warning: require (/home/meusite/public_html/wp-admin/wp-blog-header.php): failed to open stream: No such file or directory in /home/meusite/public_html/wp-admin/index.php on line 17
Fatal error: require (): Failed opening required com / (include_path = '.: / usr / lib / php: / usr / local / lib / php') in /home/meusite/public_html/wp-admin/index.php on line 17
It only displays messages and does not access the dashboard.
