Error After Update Joomla 3 To 4
Marco
Hi all,
I got the following Error on my website:
require_once(JPATH_LIBRARIES.'/joomla/document/html/renderer/head.php');
Now i changed this script with:
$header_contents = ''; if(!class_exists('JDocumentRendererHead')) { $head = JPATH_LIBRARIES . '/joomla/document/html/renderer/head.php'; if(file_exists($head)) { require_once($head); } }
After this i get an other error :(
call to undefined method joomla\database\mysqli\mysqlidriver::geterrornum()
Can anyone help me out here :)

Accepted AnswerAdvice:
Always check if all used extensions (components, modules and plugins) and default template are 100% ready for Joomla 4.0.x before upgrade. If you are not sure just check on developers websites, one by one. Joomla testing tool is not always perfect.

Accepted AnswerHoi,
contact with Template developer from where you downloaded WT Inspire Pro. Maybe he has a new version of template ready for Joomla 4. Right now it seems to be version for Joomla 3.x only. Opss.. you cannot use it on J4. You have to recover website from backup. I hope you have it.

Accepted AnswerAah thats to bad. I hoped i could change this template a little bit and get it working. I have made an backup before upgrading :)
thanks for the advice.

Accepted AnswerDon't rush. Joomla 4.0.x has many bugs. You can wait next 1-2 months to reduce possible problems. Joomla 4.0.8/9 should be fine :)
