When I upload and extract the plugin .zip to bl-plugins the plugin shows in Bludit admin page plugins, but then when I click "Activate" the link .../install-plugin/pluginRedirectPages return with "500 internal server error".
The plugin does not work with PHP 8.
I asked ChatGPT to update it. He gave me the following code for the file plugin.php:
Code: Select all

$slug = trim($url->slug(), '/');
if (!isset($redirects[$slug])) {
return; // kein Redirect für diese Seite
