To do this, access your WordPress files using an FTP client and navigate to the /wp-includes/ folder. Download all the files in this folder to your computer. Then, delete all the files from the /wp-includes/ folder on the server. Finally, upload the files from your computer to the /wp-includes/ folder on the server.

  4. Check the .htaccess file: Make sure the file is set up correctly and is not corrupt.
