 * When trying to update to the newest version of WordPress, I get this message:
   “
   The update cannot be installed because we will be unable to copy some files. 
   This is usually due to inconsistent file permissions.: wp-admin/includes/update-
   core.php
 * Installation Failed”
 * I contacted my hosting service, but they are completely unhelpful. Any thoughts
   or suggestions?
 * Thank you so very much.

 * Get a new hosting service – really 🙂
 * What kind of hosting do you have? Company, Linux, Windows, Shared, VPS?
 * You need to access the server and change the file permissions or you can try 
   a manual install which should set them based on your user login.

 * Company. The group I work for loves them, so it’s impossible to change. I have
   very limited understanding of how websites work, and I must admit, the file permissions
   page you linked is practically Greek to me. In the past, I have always automatic
   updates. What does a manual install look like? Sorry for my limited understanding!

 * You [download the latest copy of WordPress ](https://wordpress.org/download/)
   to your computer. Unzip it in a folder. Then connect to the WordPress folder 
   on the server using FTP or the File Manager in your Hosting Control Panel. You
   want to replace all of the files EXCEPT the /wp-content FOLDER and the wp-config.
   php FILE. Upload the other folders wp-includes, wp-admin, and the other files
   from your local machine and overwrite whats there. It’s deemed better to delete
   the files on the server first as some file managers will just skip an existing
   file and won’s actually over write it however if it works it works, if it doesn’t
   then you can delete first and then re-upload. DO NOT DELETE the wp-content folder
   or wp-config.php file!
