I notice the WP_DEBUG still disabled in there. In this case, i can’t enable it from WP Admin of your site, i will need FTP access to your server to enable it.
Also, please increase the PHP version on your website. You can ask your hosting administrator to update them. For the FTP access, you can send it here and don’t forget to check Set as private reply option below, i will try to do further investigation on your website.
