2 computers and 2 installed copies of the XF on the localhost for testing. Yesterday I updated the first copy at home with beta 3. Then I updated a couple of styles. I exported the XML files and take them to work. At work, I also updated the forum with beta 3. I'm trying to import styles and get an error. On a computer at work, I use the XAMPP server 1.7.4 (PHP: 5.3.5). Although previously hadn't any problems.
