post.php returns a blank page

hello guys. I have almost tried everything to fix the global error. Tried to update my .htaccess and blank spaces after ?> but none of that work. But after enabling the debug option i came to know this

Parse error: syntax error, unexpected $end in /home/pornxfai/public_html/69download.com/wp-admin/includes/class-wp-posts-list-table.php on line 247

I can’t edit my posts or pages or even see them. But everythings are great as far as i know. Please tell me how to solve this
