Steps to reproduce the issue

Module doesn't add active class on active category url. In file tmpl/default_items.php line 13 there is a code line
if ($_SERVER['REQUEST_URI'] === JRoute::_(ContentHelperRoute::getCategoryRoute($item->id))) echo ' class="active"'; ?>> <?php $levelup = $item->level - $startLevel - 1;

Expected result

if ($_SERVER['REQUEST_URI'] === JRoute::_(ContentHelperRoute::getCategoryRoute($item->id)))

It should be true but it returns false

Actual result

var_dump(trim($_SERVER['REQUEST_URI'])); var_dump(trim(JRoute::_(ContentHelperRoute::getCategoryRoute($list[0]->id))));

Get

string(60) "/index.php?option=com_content&view=category&id=10&Itemid=105" string(72) "/index.php?option=com_content&view=category&id=10&Itemid=105"

System information (as much as possible)

SEF turned off

My Solution

change 13 line php code into
if (htmlspecialchars($_SERVER['REQUEST_URI']) === JRoute::_(ContentHelperRoute::getCategoryRoute($item->id))) echo ' class="active"'; ?>> <?php $levelup = $item->level - $startLevel - 1;
