I upgraded WP3.2 to WP3.2.1, so my WP site does not work...
As a result of testing, I found out the tentative method for solving this issue.
- Download or copy "compat.php" for WP3.2 to wp-includes/ folder.
Maybe, I think that the trouble is the JSON compatibility for a plugin.
Because the issue solved when JSON module in PHP 5.3.6 was disabled.
