So it turns out it wasn’t anything I did re: the change of themes, it’s a small problem with the Mandigo theme not linking to the theme options page in WordPress v3 correctly.  I can work around it for the time being, although I am hankering for a new look for the site (but still want to keep / use some of the header images).

The new default theme is okay but it’s all so big and I much prefer small sites.  I guess I can edit the theme options and have a play.

Anyway, I finished my little plastic knight, and it’s not a half bad job considering.
