[SOLVED] Registration, log in, and password recovery pages not available

My blog doesn't show any registration, login and password recovery possibilities. And I haven't found any option to enable them.

Using the "Social Connect" plugin, I was able do add registration using social networks IDs but I still don't have registration using user name and password, nor login or password recovery.

I tried the "Theme My Login" plugin and it doesn't add anything.

Could it be because I use my own code for the header and menu ?

Using Wordpress 3.2.1 and Atahualpa 3.6.7.

Here is the URL of my work-in-progress blog:

Thanks for your help
