I had multisite working on a server with older version PHP. In order to upgrade to WP 3.2.1 I had to ask my host to upgrade to higher PHP version. I backed everything up, and after upgrade moved the files back to the server, restored the database, I made the .htaccess writable and I was told the wildcards were also set up. The main site is working, but the subdomains show only default Plesk index page. Even when I create new sites, it's the same problem. Do I need to restore the backup in different way, or am I missing something?
Thanks for any help!
[edit: maybe worth mentioning that main domain only works without www prefix, with www it shows default plesk page too)
