Ok so I add
define(‘WP_DEBUG’, true);
into wp-config.php and see the following:
Notice: unserialize() [function.unserialize]: Error at offset 0 of 401 bytes in /var/www/virtual/xxxxx/wordpress/wp-admin/includes/theme-install.php on line 59
Looking at that file around line 59 I see that the remote host for the themes API is ‘http://api.ww.wp.xz.cn/themes/info/1.0/’ which I put into a browser and subsequently receive a 503 Server Busy error.
I suspect then that this will be a temporary problem.
I have the same problem on a fresh install of 2.9.2 on a Linux host. I do have other older versions installed and they seem to be able to load the themes.
