On my boonex 7.1 site I've run into an odd error with Avatar uploads. this happens on all browsers I've tested, IE, Firefox and even Chrome for iPad.
The first screen shows the initial errors in the Avatar page. It already has an upload error on loading the page. Once selecting a file to upload, it thinks then goes to the error page shown on screen 2.
since Roansgroup.com is a social events site, the profile/Avatar picture is very important. Since it does not have the option for Profile picture on account creation, I'm sort of stuck needing Avatar.
I've also tried including the profile picture in account creation, but it conflicted with the facebook connect.
