Exception on Kirby 4

[schrockwell]

Is Kirby 4.x supported? I am getting the following error on Kirby 4.0 and 4.1.0-rc.2.

:  During inheritance of DOMDocument: Uncaught Whoops\Exception\ErrorException: Return type of JohannSchopplich\HTML5DOMDocument::loadHTML($source, $options = <expression>) should either be compatible with DOMDocument::loadHTML(string $source, int $options = 0): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in my-project/site/plugins/kirby-highlighter/classes/JohannSchopplich/HTML5DOMDocument.php:37

Hi there! Unfortunately I'm no longer actively developing the highlighter plugin. You can book some consulting to let us find the bug. But since I don't use this plugin myself anymore, I probably won't take the time to take a look into the issue. I hope you understand that. 🙂

PR is always welcome, of course. If you add support for Kirby 4, I will gladly merge it.

Understood!
