All-in-all, the v3.35 install went quite smoothly, though I did have some issues with getting StyleCatcher, the included style management plugin, to work properly. Looks like I'm not the only one... Symptom: Ability to select thumbnail from repository, reciept of successful install, but resulting in a blog with no style for most (though not all) selected styles.
The fix for me turned out to be very straight-forward, i.e., the Theme Root URL was incorrect. As with most MT installs, after unarchiving the tar.gz to the cgi-bin directory, we are instructed to re-locate the mt-static directory to an accessible location. StyleCatcher, unfortunately, is not saavy enough to check mt-config.cgi for the mt-static location. Instead it defaults (in my case) to .../torque/cgi-bin/mt/mt-static/themes rather than .../torque/mt-static/themes. Corrected, the plugin works as promised. The current template is Fleur by Jennifer Maloney.
Once you get it going, you might be interested in locating other StyleCatcher repositories. Here's my list (with appropriate Theme or Repository URL):
- SixApart - http://www.sixapart.com/movabletype/styles/library
- thestylecontest - http://www.thestylecontest.com/browse
- thestylearchive* - http://www.thestylearchive.com/browse
*Very much related to "thestylecontest".
