I have trouble when enable the cnf, I can't login and ping the server. So I contact the hosting provider to turn off the cnf and now I can login and ping it again. After adding my IP to csf.allow and add to csf.ignore and remove from csf.deny, I try to reenable the csf but I got blocked again. Can anyone suggest me what should I do? Note: This is happen after I transfer file from my another server. Because I can't transfer so I disable the cnf, after all transfer is finish I enable the cnf and now I got this problem.
