I have upgrade WP to 2.2. Looks nice. Widgets are all cool as well. There is only one problem for me now – SpamKarma 2. When I am trying to activate it, something is going wrong with the headers and I get offered to download plugins.php file instead of the plugin to start working. Due to this problem, I had to put manual comments moderation until I find a solution, so if you can not see your comment after you posted, then it is in a moderation Q.
