Log in Button overlap

Hello,

First of all, thanks for this plugin. It´s a great job.

I installed the plugin and there are a few thing that are not working for me:

1) The spacing for the button, as you can see in the footer of my website and in the Register Page, the button is overlapping one of the fields above.

2) The widget links “Ovido su Contraseña?” (Forget password) and ” Registrarse” (Register), can I put them below the button?

3) Is there a way to change the width of the fields of the form? I want to make the fields in the Register Page bigger. Also in the footer widget (not as big as in the register page.

I Hope you can help me.
