Hello.
One of my servers is updated to PHP8. It seems that most of the templates get a fatal error when moving to PHP8. For example JP Medical gives errors like:

Fatal error: Declaration of Warp\Dom\Element::before($data) must be compatible with DOMElement::before(...$nodes):
Warning: Trying to access array offset on value of type int in /templates/jp-medical/warp/src/Warp/Config/Repository.php on line 243

How can I solve this fatal error ?

Hello, all warp7 themes are not working with php8. Swich back to php7 or use the new medical theme with astroid framework.

thank you for your feedback.
Will all themes have an updated version ? I'm also using IMO.
Is there a way to check which templates are PHP8 compatible ?
Thanks!

See #2
If you have Warp7, it will not work with PHP8
If you are using Astroid-Framework, it will work with PHP 8
