google analytics not showing any data

I have problems with Google Analytics.

I placed the GA code for website with subdomains and one main domain just above the </body> tak in footer.php as my site uses subdomains (polski.fashioner.com and fashioner.com).

Despite that after over 36h since installation, GA raport shows me no data for the website and on the same time GA website profile status shows that the data is gatering (although this profile was gathering data earlier when there was no wordpress installed but simple blank page with only a logotype).

What can be wrong? :/
