I just set up the blog cecylia.com
There isn't any content on it yet (except for a test post) and I've installed some themes and a Google Analytics plugin (currently disabled).
First problem: When I try to add categories, either in the Add new page in the categories sidebar or in the dedicated categories admin page, it doesn't add a category AND the home page of the blog appears in what appears to be an error box (making the whole page look very strange). You can see the problem at
Second problem: When I look at the blog using IE7, (or the IE renderer in Firefox) it renders and scrolls very very slowly.
