Can someone help with a WordPress undefined function?

Good morning, I have my website mounted with a template in word press, I was working quietly and suddenly this error:

error 500

**Fatal error: Uncaught Error: Call to undefined function nocache_headers() in /home/u248341626/domains/nodomed.com/public_html/wp-admin/admin.php:36 Stack trace: #0 /home/u248341626/domains/nodomed.com/public_html/wp-admin/nav-menus.php(13): require_once() #1 {main} thrown in /home/u248341626/domains/nodomed.com/public_html/wp-admin/admin.php on line 36**

Someone can help me, I have no programming or development knowledge and I don’t want to start the whole page over.

    It’s Seem Directory And Permission Error
    Try To Set

    All directories must have 755 rules, for all files set 644 rules
    Also, try to set read-only attribute for wp-load.php

    Reinstall your WordPress then check your website. If you get the same error after some time, then Go to Cpanel > File Manager > Search for the wp-load.php file. change the permission to 644. Make the file permission read-only
