Login and registration problem

I have just set this template online, but I do have a problem with the registration and login link, in the top right corner, topnav menu.

When I click on 'login' the login popup should appear. But nothing happens, while locally it works perfectly. In the menu I use 'login' as link attribute, but it seems that I miss some other setting...

When click on 'register' I get a 404 error. Strangly, when I use the Firefox browser, it is redirecting to the registration page as it should be. But in Internet Explorer it doesn't...

I can't figure it out what I am missing here. Searching for hours now...

Can someone help me out with this? Its about this website: http://www.simplicitaz.nl

For the information: other popups do work correctly.

Popups from other menu's and the popup from 'my cart' are working as it should.

Hello,

Did you published the module on the login module position?

Yes, which is position 'topmenu', the same as the demo of this template. Still can't figure it out why it isn't working

I'm not sure if you understand - I mean that you have to publish login module on the "login" module position - then the popup should appear after clicking the login button.

I think so... I just PM'ed you about this.

Aah... I checked it again and the login module wasn't publish correctly. I did now and it is working Thanks!
