Aplus PHP and 302 Found error

Hi,

I have recently setup the latest version of WordPress on my Aplus hosted site (soloXP package). It works, hoswever after any post type activity (login, new post etc) I get the error shown below. However if I just type my base URL back in firefox after the error it will take me back to my wordpress blog with the action updated (i.e I will be logged in, or the post will have been accepted).

Can anyone advise if there is anything special I need to do on Aplus PHP or anything to solve this?

Cheers,

Daz
