hi @mercime – FYI- i upgraded to the latest version of buddy press and this has resolved the issue
from the previous version of wordpress to WordPress 3.5.1. – i didn’t upgrade buddypress as i had made some modifications to the layout. Everything else works bar the avatar upload/change. When this is changed there is a blank page and hang type behaviour. I’ve tried various permetations of permissions but with no success.
I had this working and upgraded wordpress and this seems to have broken this functionality – perhaps there is a bug to be investigated?
