If LiceBase looks funny on Internet Explore (IE):

There is a bug in IE that doesn't allow to process more than 31 css links and Microsoft possibly won't fix it.

Internet Explorer is just broken....

We have installed a module to circumvent this (IE Unlimited CSS), however we also have enabled the Color module which interferes with it.

Therefore, after each update of Drupal core, we have to apply the patch described in the following post as well:
https://www.drupal.org/node/445138

In themes/garland/template.php, change the following function to look like this

/**
 * Override or insert PHPTemplate variables into the templates.
 */
function phptemplate_preprocess_page(&$vars) {
  $vars['tabs2'] = menu_secondary_local_tasks();

  // Hook into color.module
  if (module_exists('color')) {
    _color_page_alter($vars);
  }
  // solution from: https://www.drupal.org/node/445138
  // Hook into unlimited_css.module
  if (module_exists('unlimited_css')) {
    unlimited_css_preprocess_page($vars);
  }
}
