 * GET HTTP 403 Forbidden 20140 ms
    Probing for vulnerable PHP code Denied
 * wpcerber info.
 * REDIRECT_REDIRECT_HTTP_COOKIE **wp-saving-post=**“**MY POST NUMBER**“-saved; 
   wordpress_078f20………………….. a lot of info!
 * SCRIPT_URL /wp-admin/admin.php
    REDIRECT_URL /503.shtml wp-saving-post 4509-saved——————————————–
 * I have made multiple attempts but the error persists
    i did: 1- [https://wpcerber.com/wordpress-probing-for-vulnerable-php-code/](https://wpcerber.com/wordpress-probing-for-vulnerable-php-code/)
   2- Clear cache 3- turn off the plugins 4-d elete the post and create them again

    Note: it’s as if something was in memory pending, that when I navigated the
   administrator site “WP” trying to do something to task to save the “F…” post.

 * Hi! It’s caused by another plugin or piece of code. This line looks suspicious
 * **REDIRECT_URL /503.shtml**
 * Frankly, I don’t completely understand what you’re talking about. Use the Live
   Traffic or Activity log to find out the cause. If WP Cerber blocks a request,
   it always logs the reason for it.
