VirtueMart Login Refreshing Blank Page?

Hi there,

It seems that when a current user tries to login to finish the checkout process it just refreshes on a blank page and keeps logging them in as documented by the admin panel, but they just get a blank page that keeps refreshing. I'm assuming it's something with Virtuemart, but I cannot be sure.

Has anyone else had this happen? If so, is there a solution?

Clearly not a designed benefit of the login

Have not heard of such problem before. Does your VM work OK without Joomdle ie just purchasing other products?

No, unfortunately it doesn't work. Keeps refreshing. I emailed Antonio about it yesterday. He's gone through the site and is having problems finding anything wrong. Strange...
