Problem vyrieseny.
1) Vstupit do adresarovej struktury Joomla do priecinka:
.../components/com_content/views/article/
2) Otvorit subor view.html.php
3) Najst textovy retazec
"$this->params->def('page_heading', JText::_('JGLOBAL_ARTICLES'));"
4) a dopisat pred neho 2 lomitka, t.j. z prikazu spravit komentar
//$this->params->def('page_heading', JText::_('JGLOBAL_ARTICLES'));
5) Overene - funkcne.
6) Good Luck
