The W3C Validator comes up with the following error:
Line 11, Column 110: & did not start a character reference. (& probably should have been escaped as &.)
…pis.com/css?family=Caesar+Dressing:400&subset=latin' type='text/css' media='al…
I don't know a lot about PHP, but went into the
google-fonts.php file anyways and escaped the ampersand on line 1197 like this:
$query .= "&subset=" . implode(",", $subsets);
Still got the same validation error, though.
