ADMINISTRATOR READ ASAP
your website is vulnerable of sql injection
NOTHING WAS MODIFYED/DELETED ON THE WEBSITE
i decided only to put this advice here to correct the error as soon as possible for avoid more users to enter in the admin login.
here is the link for the page used in the sql: http://www.finanzasparatodos.org.mx/finanzasv2/public/view_cat.php?id=20
hope you correct this QUICKLY because is a VERY dangerous error
