solved using apache redirect
Updating it to 3.9.x solved the problem
I Forgot to mention, that is the problem, all right, I can use domain.com:3681 but I use free DDNS and to avoid it’s iframe (with adv) I want to use that javascript.
I will take a look at this plugin
No one will even try to help me to solution my problem? or at least point me to a doc or anything that can help me?
