ERROR 403 Hotsgator

My is returning ERROR 403. The reason is Hostgator’s security policy, it thinks this is a hacker attack or something. But I found that if I just take the “HTTP” from the link it works. Here are examples:

This one does not works: http://www.dhammadafloresta.org/blogger/?q=http://dhammadafloresta.blogspot.com/2014/10/guerreiro-ou-fujao.html

This one works fine: http://www.dhammadafloresta.org/blogger/?q=dhammadafloresta.blogspot.com/2014/10/guerreiro-ou-fujao.html

The only difference is the removal of “HTTP://” from the beginning of the argument. Would it be possible to change the plugin to take care of this? I looked around in several sites and a lot of people are having this problem. I would appreciate it a lot. Thanks!
