Whenever I call SLA plugin from the frontend (to allow users change their avatars) wp_handle_upload() -called from edit_user_profile_update()- displays this error: "There was an error uploading the avatar: Specified file failed upload test." Additionally, translated strings don't display.
However the avatar deletion and change is always successful. Will it be a security issue to override the upload test? Is it due to creating an instance of Simple Local Avatars class from another class in the frontend?
Thanks in advance for your answers,
