 * I made some changes to my website (which includes my WordPress blog) and uploaded
   the whole site, which I guess I shouldn’t have done.
 * When I tried to go into my blog, here’s what I got:
 * Fatal error: Call to undefined function: setup_userdata() in /home/playtee/public_html/
   WP/wp-includes/pluggable-functions.php on line 21
 * Any ideas on what I need to do to overcome this problem.

 * that function is defined in wp-includes/user.php
 * you need to upload ALL the files, specifically wp-includes/user.php .
 * You either didnt upload that file, or you didn’t follow the instructions when
   upgrading, (ie, delete ALL the wordpress core files, etc.. and then upload the
   fresh ones) or whatever you used to install/upgrade didnt provide the correct
   file.
