EDIT: I've now solved the problem; I hadn't realised that, when importing my blog from Wordpress.com to my own host, a lot of my posts had lost their categorisations (although they still displayed on the posts, strangely.) Thanks anyway!
I'm hoping someone can help out a newbie fumbling around with Atahualpa!
Since installing the theme it has only ever displayed 11 out of 24 categories and I can't seem to spot a setting in the Atahualpa Theme Options that would alter this. This category list is in the default position on the left hand side of the screen. I've added a new category, which appears on the list, so it seems that it's just the majority of the original categories that aren't appearing.
Does anyone know of a solution to this error, or would it simply be easier for me to reduce the number of categories I use?
I'm using Atahualpa 3.4.1 with Wordpress.org version 2.8.4
Thanks in advance for any support!
