I'm on latest stable BP and just upgraded your plugin which had some issues with uploading stuff on my install.
Good news is that the upload part works better now (thanks), bad news is that the plugin does not seem to load on the home page anymore (home page is same as /activity on my setup). All groups, profile pages and /activity url work though. It's just the home page in which nothing is loaded, not even the thickbox plugin.
Any hint ?
