Hello,
I discovered that the truncation in default.php is wrong.
This can be sloved by using the better truncate function (more parameters).
See:
api.joomla.org/cms-3/classes/JHtmlString.html
// echo JHtmlString::truncate(strip_tags($item->introtext), $introtext_truncate);
replace by:
echo JHtmlString::truncate($item->introtext, $introtext_truncate, true, false); ?>.
Best regards,
Peter
