Error in wp-settings preventing site access

Hi

Seems to be some wordpress core files is missing. Please reupload the wp-includes folder and its files.

(Please use correct wordpress version files)

(Pleas keep a backup of both files and database)

Try re-uploading all files & folders – except the root wp-config.php & .htaccess files and the wp-content folder – from a fresh download of WordPress. Make sure that you delete the old copies of files & folders before uploading the new ones.

Your site’s content is all stored in your database – with the exception of uploaded media files stored in the wp-content folder. So as long as you avoid that folder, you will be fine. All you are doing is uploading a fresh set of WordPress core files.

I’ve just discovered the problem or a similar problem exists on other WP sites I maintain (total of 3 now). I’m not sure if this is related to a WP upgrade? Here are the URLs and error messages:

Applying a solution from the responses above, I have resolved this issue. The process I used was:

1. Using my web host File Manager, I deleted the wp-admin and wp-incudes folders, and the last plugin that I added as I thought it could be causing a conflict (wp-content/plugins; delete respective folder)

2. Download a complete copy of wordpress from www.ads-software.com

3. Using an FTP Client (I used ForkLift on my Mac), I uploaded new copies of wp-admin and wp-includes

4. Visited the site and logged in to confirm the site worked. I was 3/3 for affected sites
