Page redirect after login

Hi,

I'm having trouble with the page redirect after the user logs in on crm portals. After the user logs in, the site redirects to the profile page, and not the last page the user was on. I've read that this occurs when the profile form isn't completed, however in this case the profile form is completed and I can't find any  more required fields in CRM to assign a value to. 

Thanks in advance.

Sam
