Fatal error: __autoload() is no longer supported, use spl_autoload_register() instead in /home/storage/736/3736736/user/htdocs/wp-includes/compat.php

Question

My wordpress website is getting the below error:

Fatal error: __autoload() is no longer supported, use spl_autoload_register() instead in /home/storage/736/3736736/user/htdocs/wp-includes/compat.php on line 502

From review of other tickets I updated line 502 with:

function spl_autoload_register( $classname ) {
    ...
}

However I now get the below error:

Warning: Private methods cannot be final as they are never overridden by other classes in /home/storage/736/3736736/user/htdocs/wp-includes/class-wp-session-tokens.php on line 71

I am using WordPress.

Can anyone please help?

You may face an issue with your PHP version. I also faced the same issue. My website was not compatible with the latest PHP version. I changed the PHP version to 7.4 and it works for me.
