 Hi,

 on a fresh install of WordPress 4.9.8 :

 http://sub.yourdomain.com/?xtor=AD-4970-%5BSocial%5D-%5B%5D-%5BPPL%5D-%5BFacebook%5D-%5B228284160&105478095%5D-%5B0%5D

 will be redirected to :

 http://sub.yourdomain.com/?xtor=AD-4970-%5BSocial%5D-%5B%5D-%5BPPL%5D-%5BFacebook%5D-%5B228284160&105478095]-%5B0%5D

 Problem is : it does an 301. And, combined with Facebook mobile on Iphone
 link to the WordPress, it retries forever. 21 000 hits / 5 minutes on our
 server. Glad it was strong enough to sustain until we find the bug and
 temporarily deactivated
 {{{
 redirect_canonical
 }}}

 with :
 {{{#!php
 <?php
 remove_action('template_redirect', 'redirect_canonical');
 }}}
