Answer 1

Check if $site_URL Variable is correct in config.inc.php file? also you can disable this error by editing the following file includes/http/Request.php

around line 207-207 on validateReferer function find

        throw new Exception('Illegal request');

change to

        //throw new Exception('Illegal request');
