Hello

I'm trying to update to php 8. Got following error:

Fatal error: Declaration of Warp\Dom\Element::before($data) must be compatible with DOMElement::before(...$nodes): void in /customers/c/e/0/zwemclub-bst.be/httpd.www/templates/jp-surfing/warp/src/Warp/Dom/Element.php on line 108

Can you help plz
Thx

Hello, JP Templates are based on Warp 7 and these are not compatible with PHP 8 or Joomla4.
You have to use TP Temlpates which are based on Astroid.
