My server has been upgraded from PHP 7.4 to 8.0.8. I know it causes because of one of the plugins named wcore admin which was developed by custom. And It's required plugin to do our jobs. I'm looking for a way to fix the issues and maintain the script myself since I'm very happy with it.

Answer 1

You should try

call_user_func_array([new $this->controller, $this->action], array $args);

Answer 2

I faced same issue on upgrade to php8.0, the error shows steps to debug

'class Wcore_Admin does not have a method "sitemap_exclude_post_type"'

the plugin or file class name Wcore_Admin does not have a function named sitemap_exclude_post_type. Remove the line calling a missing function, and it should work

Answer 3

I have changed the php version to 7.4.30 and this solved my issue
