Hi @Onur
Thank you for your reply.
It is my own server and i dont have mod_security or cloudflare on it.
I use to run apache,nginx but have dumbed it down to pure apache with theas moduals loded.
Could it be mode_pagespeed ?
I found a way past it so its not so important atm. i created a user in whmcs with the same username as in CWP. then orderd a new service witch gave an error. then i changed password and it linked it.
