PHP Notices on 5.9.0

I got this msg on a module:
Notice: Undefined property: stdClass::$images in /home/delta/public_html/components/com_sef/sef_func.php on line 0

This is the URL:
www.deltaradiocomunicacion.com.mx/index....&Itemid=73&form_id=1

How can I get rid of it  ???

Thanks

I can't replicate. You have image-alt settings on?
Either turn off your notices (they are not errors!) or send me the FTP info and I will take a look.

I turnef off images-alt in SEO tab, worked.

Thanks
