Wrong link to BuddyPress avatars

I have problem uploading avatars on profile pages. The images gets uploaded, but the link to the image is wrong. I find the image on link http://media.lusitanoportal.com//sites/2/avatars/1/63dd0dae443e60969e2b3ec33d056a70-bpfull.jpg, but BuddyPress gives it the link http://forum.lusitanoportal.com/media.lusitanoportal.com/public_html/sites/2/avatars/1/63dd0dae443e60969e2b3ec33d056a70-bpfull.jpg. Where can I change this?
