   error-protection.php on line 93
 * When accessing the webspace via FTP i can see all the files.
    What i`ve already
   tried to fix it: – i deleted the cache – i renamed the plugin folder
 * Any other idea how to fix this problem?

 * Could you double-check your `wp-settings.php` file is up-to-date?
 * [Line 21](https://core.trac.wordpress.org/browser/tags/5.2.1/src/wp-settings.php?marks=21#L18)
   should look like this:
 *     ```
       require( ABSPATH . WPINC . '/class-wp-fatal-error-handler.php' );
       ```

 * `wp-settings.php` looks ok. Line21 is there.
 * [@fierevere](https://wordpress.org/support/users/fierevere/) is it save to just
   overwrite the full /wp-includes/ folder?

 * Yes its safe to overwrite, it should not contain any custom data.
