To remove the feed you should make sure there is this function in your qa-theme.php:
function feed() { }
Yeap, it is empty.
In order to remove the category counts then you'll have to add a new function to handle the recursion and make sure your doctype() function is similar to the one below, again in the qa-theme.php:
private function remove_category_count(&$category) {
unset($category['note']);
if (isset($category['subnav'])) {
foreach ($category['subnav'] as $name => $dummy_category) {
$this->remove_category_count($category['subnav'][$name]);
}
}
}
function doctype() {
qa_html_theme_base::doctype();
if (isset($this->content['navigation']['cat'])) {
foreach ($this->content['navigation']['cat'] as $name => $category) {
$this->remove_category_count($this->content['navigation']['cat'][$name]);
}
}
}
Note this is a blind shot. I don't know what your qa-theme.php file looks like. So make sure you backup the file, just in case.
