Looking at the plugin, I saw this line in the preload code:

$taxonomies = apply_filters( 'wp_cache_preload_taxonomies', array( 'post_tag' => 'tag', 'category' => 'category' ) );

So I added a filter in my child theme’s functions.php:

// WP SuperCache custom taxonomies
add_filter( 'wp_cache_preload_taxonomies', 'cache_my_taxonomies' );
function cache_my_taxonomies( $tax ) {
    return  array( 'post_tag' => 'tag', 'city' => 'city', 'county' => 'county'  ) ;
}

Now my site’s city and county custom taxonomies are cached. Yey! I do not want categories cached, that’s why 'category' => 'category' is not in the array in my filter.

Yuffie89 – FWIW, I installed iThemes Security on a new site, and within 24 hours it had prevented several invalid login attempts and one brute force attack. This freaked me out enough to risk upgrading from 3.6.6.

I created a full backup, plus made my own copies of .htaccess and wp-config.php. I read through this post, http://wordpress.org/support/topic/better-wp-security-is-officially-ithemes-security?replies=29, plus several of its links. Armed with the phone number of my web host in case something went terribly wrong, I pressed the “update now” option.

This went fine! I rechecked all settings and adjusted a few to be more stringent. All is great and my site is working with no issues.

I don’t use many plugins, so maybe that is a factor. But I just thought you’d like to hear this success story. Good luck with your upgrade!
