Fatal errors

Hello guys,

I have lots of Soft 404 errors in my google webmaster tools.

Most of them, have urls with the following error:

Fatal error: Class ‘Requests_Exception_HTTP’ not found in /home/user/public_html/wp-includes/Requests/Exception/HTTP/416.php on line 13

(…)

Fatal error: Call to undefined function feed_content_type() in /home/user/public_html/wp-includes/feed-rdf.php on line 8

Fatal error: Call to undefined function _deprecated_file() in /home/user/public_html/wp-includes/session.php on line 8

Fatal error: Call to undefined function is_robots() in /home/user/public_html/wp-includes/template-loader.php on line 28

Fatal error: Class ‘SimplePie_Cache’ not found in /home/user/public_html/wp-includes/class-wp-feed-cache.php on line 17

Fatal error: Class ‘Walker’ not found in /home/user/public_html/wp-includes/class-walker-category.php on line 17

Fatal error: Call to undefined function is_main_site() in /home/user/public_html/wp-includes/update.php on line 739

Can someone help me? I’m using the latest wordpress version (4.9.8).
And I think that most of these errors appeared when I upgrade to the latest version.

Thank you in advance.

Regards,
Tim
