Can not get into admin login

[reactbiz]

Hi
I just installed latest version of PrestaShop on addon domain on BlueHost server. Front-end works fine but when I try to go to admin panel www.wellwisdom.co.za/rm1953 it goes straight to front end. I checked error log I get this message:
PHP Startup: Unable to load dynamic library './php_gd2.dll' - ./php_gd2.dll: cannot open shared object file: No such file or directory in Unknown on line 0.
And this message:
PHP Startup: Unable to load dynamic library './magickwand.so' - ./magickwand.so: cannot open shared object file: No such file or directory in Unknown on line 0

But Gd is installed and setup (see here http://www.wellwisdom.co.za/info.php).

Can anyone help?

Regards
