Problems using the plugin

Hi,

I have installed and configured the plugin with success. I positioned it as i would like it to be and everything is ok .

The problem is :

– When i register and i try to login, i am unable to do so and i am redirected to a second page.

Is there anything i can do for this ?

Thanks in advance.
