Moved from root directory to a sub directory

Hi all,

url: http://www.advghana.com/designs

My site was previously installed in my root directory until just last night i decided to move it to its directory in order to keep the root directory clean for other purpose.

After moving the files from the root to a sub directory my site is not showing and it giving an error message on the page of the url above. I must ve gotten something wrong.

Please i need your help.

Thanks indeed
