When I press update, a row with the <th>xxx</th> key gets changed to
<tr>Header1 Header2 Header 3</tr>
It was working a few days ago, because I did it then.
Also I was wondering about the gallery format. In the demo blog for my TwnetyTen the gallery has all the thumbnails on the main page. When I do it, I get one thumbnail and a line that says “X photos in the gallery” and the thumbnails are on page 2.
