Help! if i go to my website i get a blank page!

[Marlake]

Hi:

I moved all of my files that were in the directory "store" in the root.

if i go to my admin seems to work fine (after I fixed some errors in the configure.php file)
Is fine if I write this:
www.mhi-ramps-and-lifts.com/admin

BUT if I put just my domain name:

www.mhi-ramps-and-lifts.com

I just get a BLANK page, nothing!


If i go from my admin to "online catalog" what i read In the browser is:
http://www.mhi-ramps-and-lifts.com/index.php?main_page=

BUT still NOTHING JUST A BLANK PAGE
I have not clue what the problem is.
I would appreciate any possible help on this.
THanks,
Marlake
