   In my admin, I can add categories and delete them no problem. I can also create new posts, but when I try to view them, I get the following error:

   WordPress database error Table 'wordp.wp_categories' doesn't exist for query SELECT category_parent FROM wp_categories WHERE cat_ID IN (10) made by require, require_once, include, get_sidebar, locate_template, load_template, require_once, is_child, is_child_getParents WordPress database error Table 'wordp.wp_categories' doesn't exist for query SELECT category_parent FROM wp_categories WHERE cat_ID IN (10) made by require, require_once, include, get_sidebar, locate_template, load_template, require_once, is_child, is_child_getParents WordPress database error Table 'wordp.wp_categories' doesn't exist for query SELECT category_parent FROM wp_categories WHERE cat_ID IN (10) made by require, require_once, include, get_sidebar, locate_template, load_template, require_once, is_child, is_child_getParents WordPress database error Table 'wordp.wp_categories' doesn't exist for query SELECT category_parent FROM wp_categories WHERE cat_ID IN (10) made by require, require_once, include, get_sidebar, locate_template, load_template, require_once, is_child, is_child_getParents WordPress database error Table 'wordp.wp_categories' doesn't exist for query SELECT category_parent FROM wp_categories WHERE cat_ID IN (10) made by require, require_once, include, get_sidebar, locate_template, load_template, require_once, is_child, is_child_getParents

   This error makes no sense. If the wp_category doesn't exist, then where are these categories being stored?

   I suggested upgrading the WP version, but other than that, what else can be causing this?

   I forgot to mention that this is on IIS server... unfortunately.

   Are they really running WordPress version: 2.8.4?

   If you look here at the database description for that rev, you'll see there is no table 'wp_categories'. It's likely an outdated plugin during the view (which is why the admin level add categories is not effected).

   Thanks Geistvox... I think that you're right. The is_child plugin seems to be the culprit.
