salvomic Hi. I've made a workaround and edited file /html/com_content/article/default.php
I've commented out this part:
if ($params->get('show_intro')) {
$separator = md5(time());
$this->item->text = $this->item->introtext . $separator . $this->item->fulltext;
$offset = $this->state->get('list.offset');
$dispatcher = JEventDispatcher::getInstance();
$dispatcher->trigger('onContentPrepare', array ('com_content.article', &$this->item, &$this->item->params, $offset));
$dispatcher->trigger('onContentAfterTitle', array ('com_content.article', &$this->item, &$this->item->params, $offset));
$dispatcher->trigger('onContentBeforeDisplay', array ('com_content.article', &$this->item, &$this->item->params, $offset));
$dispatcher->trigger('onContentAfterDisplay', array ('com_content.article', &$this->item, &$this->item->params, $offset));
$explode = explode($separator, $this->item->text);
$this->item->introtext = array_shift($explode);
$this->item->text = implode('', $explode);
}
and added this small code at the bottom of this file:
<style type="text/css">
blockquote.article-intro {
display: none;
}
</style>
at least it's not showing double now. Please check.
