I want to use this plugin - http://wordpress.org/extend/plugins/simple-local-avatars/
I installed it, activated it, everything was fine. But when I try to upload an avatar, this error appears:
Fatal error: Call to undefined function wp_handle_upload() in /home/account/public_html/wp-content/plugins/simple-local-avatars/simple-local-avatars.php on line 197
Can you please tell me how can I fix this problem?
Thanks in advance
