I've installed a plugin to upload local avatars through a front end form to edit user profiles provided by another plugin (user frontend). While the upload and modification of the db seems to work just fine, clicking the update button of the form does apparently lead to the WP 3.1 admin bar no longer being rendered for some unexplicable reason. There's simply no $wp_admin_bar object being created. I have no idea what could possibly cause this, but I have also no idea how to activate the admin bar if the default init function fails.
Does anyone have an idea for me?
