Internal Server Error on new subdomain multisite. Help!

Hi experts and friends,

I just set up a multisite following all the instructions from http://codex.wordpress.org/Create_A_Network to the T. Everything worked, i was able to set up new sites using subdomains. I then had problems opening the dashboard of the new subdomain site en.mydomain.com/wp-admin — it a Internal server Error page came up, but when i directly accessed the new site en.mydomain.com the default Bluehost (my host) page pulled up. i’ve tried manual installations, I’ve tried Simple Scripts installation then modified the wp-config file, but to no avail. I tried resetting my wildcard domain as per the suggestions of the solution recommended here http://wordpress.org/support/topic/404-error-cant-figure-out-how-to-create-a-multi-site-network?replies=13.

Any ideas?
