Hi Robert,
I noticed something strange. I have 2 categories with HTML tags in their name, to put some emphasis on the categories list, but when I go the the category page, I see the tags written there as text. I give you a concrete example, one of them is <b>Christmas Specials</b>, and it works ok in the categories list as the name in Bold, but when I load the category page I see <b>Christmas Specials</b> as the title. The title meta tag is ok.
I see the same behavior in the breadcrumb, but maybe here is not due to your contribution.
I tried to change in index.php from
echo KissMT::init()->page_title . PHP_EOL;
to
echo strip_tags(KissMT::init()->page_title) . PHP_EOL;
but the tags are still there. I tried also to change the strip_tags to htmlspecialchars and it works as expected so I'm on the right place...
You can have a look at the page here:
