   Upgrading from 2.1 to 2.5 - I removed the old wp-includes and wp-admin and uploaded the new folders.

   When I went to the page on my site equivalent to
   http://example.com/wordpress/wp-admin/upgrade.php.

   Warning: Invalid argument supplied for foreach() in .../wp-includes/query.php on line 683

   Fatal error: Call to undefined function update_object_term_cache() in .../wp-includes/post.php on line 2745

   I tested this out on another version first, going from 2.2 and it worked fine.

   Any ideas?

   I was able to fix my problem by replacing all the root files except wp-config.php and .htaccess with the files in version 2.5.1. I had already replaced the wp-admin and wp-includes files with 2.5.1 ones.

   I hope this helps.

   I'm having the same problem with line 684 on query.php

   Searching it on google I see that it is a problem on many sites. I tried replacing the files but it's still there. Anybody have a solution to this upgrading problem?

   Thanks.
