Hi,
I updated to joomla 3.8.1 and my web page appears Fatal error: Warning: require_once(/home/www/elektrahrob.cz/subdomeny/dev/libraries/joomla/document/html/renderer/head.php): failed to open stream: No such file or directory in /home/www/elektrahrob.cz/subdomeny/dev/templates/sj_thecool/error.php on line 44

Fatal error: require_once(): Failed opening required '/home/www/elektrahrob.cz/subdomeny/dev/libraries/joomla/document/html/renderer/head.php' (include_path='.:/usr/share/php') in /home/www/elektrahrob.cz/subdomeny/dev/templates/sj_thecool/error.php on line 44

Could you help me?

Dear TomasZmuda

please refer our blog here: www.smartaddons.com/blog/how-to-fix-bugs-when-update-sj-templates-to-joomla-38
to fix this issue go to file templates\sj_thecool\error.php
and find:

require_once(JPATH_LIBRARIES.'/joomla/document/html/renderer/head.php');

=> change to

require_once(JPATH_LIBRARIES.'/src/document/renderer/html/HeadRenderer.php');

thanks

Hi, thank you, I removed line 44, as is written on posted link. Now I'm getting another error: Serialization of 'SimpleXMLElement' is not allowed
see dev.elektrahrob.cz/

Dear TomasZmuda

To fix this issue, please go to modules\mod_sj_contact_ajax\mod_sj_contact_ajax.php find code:

$layout = $params->get('layout', 'default');
$cacheid = md5(serialize(array($layout, $module->id)));
$cacheparams = new stdClass;
$cacheparams->cachemode = 'id';
$cacheparams->class = 'ContactAjax';
$cacheparams->method = 'getList';
$cacheparams->methodparams = $params;
$cacheparams->modeparams = $cacheid;
$list = JModuleHelper::moduleCache($module, $params, $cacheparams);

=> edit to:

$layout = $params->get('layout', 'default');
$list = ContactAjax::getList($params);


or

$layout = $params->get('layout', 'default');
$list = ContactAjax::getList($params, $module->id);

thanks
