I've just installed it over a WP 3.3.1 installation, BP 1.5.3 the Parallellus Salutation theme (compatible as the creator confirms it), and it just keeps failing uploading a Photo. URLs and links are working fine, though.
A client just tested it, and managed to upload one photo, but failed to upload four of them. I've just been unable to upload any. It seems to upload the photo, and when the loader reachs 90%-100%, it claims "Failed", and no thumbnail is generated. Firebug displays a 404 error, and "undefined" in the image location path. Tried 777 the directory with no results, and disabling all other plugins with no results either.
