Adapte old template to Joomla4

Hi after update you can have some error on old custom template, that normal your code need to be update for joomla4

 in item.php or item_html5.php

In Joomla 3 

find

JFactory::getDocument()->addScriptVersion(JUri::base(true).'/components/com_flexicontent/assets/js/tabber-minimized.js', FLEXI_VHASH);
JFactory::getDocument()->addStyleSheetVersion(JUri::base(true).'/components/com_flexicontent/assets/css/tabber.css', FLEXI_VHASH);
JFactory::getDocument()->addScriptDeclaration(' document.write(\'<style type="text/css">.fctabber{display:none;}<\/style>\'); ');  // temporarily hide

find
JRequest::getCmd('print'))

 In Joomla 4 remplace it for

find

JFactory::getDocument()->addScript(JUri::base(true).'/components/com_flexicontent/assets/js/tabber-minimized.js', array('version' => FLEXI_VHASH)); JFactory::getDocument()->addStyleSheet(JUri::base(true).'/components/com_flexicontent/assets/css/tabber.css', array('version' => FLEXI_VHASH)); JFactory::getDocument()->addScriptDeclaration(' document.write(\'<style type="text/css">.fctabber{display:none;}<\/style>\'); '); // temporarily hide the tabbers until javascript runs

find
JFactory::getApplication()->input->getCmd('print')
