Setup Issues

I can’t put a proper title atm, cause i’m having 2 different issues just after the “setup”.

On my working site (now in maintenance to properly run it back live with Blackfyre) when I try to install the theme, it works fine, but I noticed some css problems, and I can’t make the slider work (i have ofc created a new slider, selecting the category i want for it).
Basically, I can’t build the pages as on your demo.

My second problem, is on a fresh install, loading your demo contents.
The site is built perfectly, css works fine, block are just as on the demo, but I can’t login as administrator.
Users are replaced with the custom ones you put into the demo, and “admin” – “admin” works just as a normal users login.

How can I figure it out? I can choose the second installation, cause i’m also using WP-United, so I can take all the users back with my phpbb3 db, but I need to work on it as admin 😀

Thanks for your kind effort and support!
