   Hello, I run a blog that I first set up with version 3.2.1 of WP. I recently updated to 3.3 but since then I have been completely unable to access the administrative side to my site, i.e. the dashboard or anything. My site look and runs ok to everyone else but when I try to log in as an administrator I get the following error message:

   Fatal error: Call to undefined function wp_get_update_data() in D:\Hosting\8672204\html\wp-admin\menu.php on line 34

   I have no idea what this means. I hoe it doesn't mean that my site or content was hacked. What steps should i be taking to address this issue??

   I hope it doesn't mean that my site or content was hacked.

   No, this probably means your theme or plugins are not compatible with WP3.3. Or not all files were uploaded correctly.

   read the troubleshooting 3.3 master list: http://wordpress.org/support/topic/troubleshooting-wordpress-33-master-list

   try:
   - flushing any caching plugins you might be running, as well as server and/or browser caches.

   - resetting the plugins folder by using FTP or whatever file management application your host provides. Sometimes, an apparently inactive plugin can still cause problems.

   - switching to the default theme by renaming your current theme's folder in wp-content/themes using FTP or whatever file management application your host provides.

   - re-uploading all files & folders - except the wp-content folder from a fresh download of WordPress. by using FTP or whatever file management application your host provides. (manual upgrade)

   - re-running the upgrade via wp-admin/upgrade.php

   Now the error message I am getting is:

   W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove D:\Hosting\8672204\html\wp-content\db.php.

   Ok, So I went to the FTP file manager via my hosting service (GoDaddy) and I deleted the W3 Total Cache plugin. It should be totally removed now so I figured I wouldn't see the same error message but it is still telling me the same thing.

   How do I reupload all files or reset all the plugins through my FTP file manager page?

   I know it must look like I'm totally incompetent, but I cannot find that file in my FTP File Management application. Am I looking in the wrong place? I cannot find it to delete it. Where should I be looking?

   It should be in the wp-content folder. If you can't see it with ftp try signing into your hosted account and using the file manager there.

   Did you try all that keesiemeijer suggested? Like switching to default theme and uploading new copies of wp-admin and wp-includes.

   I did delete it, a new error message came up telling me to remove a different plugin file, and I did so. Now my error message is:

   Fatal error: Call to undefined function wp_get_update_data() in D:\Hosting\8672204\html\wp-admin\menu.php on line 34

   Does this mean that I have to make some changes to the complicated file written in code? What should I do with this error message?
