My image uploader and tag input have not been working so I found an article (http://wordpress.org/support/topic/164999?replies=1). I followed the article and deleted the wp-includes and wp-admin and re-uploaded them from a new download of wordpress.
Now all I get when I go to my website http://www.dwellupon.net is:
Warning: require_once(/home/content/20/4616620/html/wp-includes/wp-db.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/20/4616620/html/wp-includes/functions.php on line 2772
I need help, what can I do to fix this?
