WAF Blocked checkout whmcs?

Hi Friends,

I performed several tests and had no problems.

But observing logs mod security, and realized that a new order was not performed because it was blocked


/painel/cart.php?a=checkout HTTP/1.1
Access denied with code 403 (phase 2). Match of "rx ((?:submit(?:\\+| )?(request)?(?:\\+| )?>+|<+)$|^< ?\\??(?: |\\+)?xml|^> ?$)" against "REQUEST_URI:\xcf\x99\xf4\xb6\x01" required. [file "/var/cpanel/cwaf/rules/cwaf_01.conf"] [line "2123"] [id "211184"] [msg "COMODO WAF: Blocking XSS attack"] [data "485"] [severity "CRITICAL"]
csf.deny: # lfd: (mod_security) mod_security (id:211184) triggered by 1 in the last 300 secs - Thu Jan 23 22:27:42 2014

Will be fixed by next update.
