OK, if you have at least 13 projects and if you have configured only the weekly for All_projects you must receive at least 13 emails (one per project).
The $g_path variable is automatically set but in the weekly plugin (especially in the weekly_send.php page) the value is wrong.
Maybe you have a "special" project that generates the access denied error.
Try to send weekly only to the administrator (for debug info).
