Can't load admin page, after changing admin folder name

[bimer]

Hi all.

 

I really need some help here.

 

I have installed prestashop 1.5, on my local server.

 

The install process succesfully ended, and I was told to delete install folder, and rename admin folder, before i could access the admin login page.

 

But, after i have changed the admin folder name, it won't show the admin login page.

see http://nas.bimer.dk/prestashop/admin123

 

Its just a white page with nothing on it.

Have installed prestashop comletely default, (US location, and timezone).

 

Hoping for some help..

 

Regards

Christian
