Hi there... I have a little problem...

I'm upgrading from 3.26 to 4.0 as I have Joomla 1.5

The installation progress is ok... I get installed normally... And in my website the comments are displayed and the previous comments too.

But in the administration page, as I try to enter to the component (settings, comments and all that stuff) I just get a blank page... I don't know what's happening...

I get the same result with all packages for 4.0:
alpha3
beta1
beta2

When I install 3.26 again, it works fine.

What can I do?

Thanx!
