Trying to install the default responsive theme that comes with CS Cart v4.2.4 results in a broken homepage due to the error below with the /public_html/design/themes/responsive/css/styles.less style sheet. Clearing the cache via the admin panel and FTP doesn't fix it. Adding a color to the line results in additional error after error found with any line that defines lighten or darken for color or background. This seems to be a common issue but couldn't find the fix using a google or forums search so any help would be really appreciated.
LESS expected color value: failed at `color: darken(@links, 10%);` line: 52
.transition(all 150ms);
}
a:hover {

ul {
